d) 140km

Let after time of 't' hrs both train meets, then
Distance covered by train leaving at 6.30 am at 30 kmph = Distance covered by train leaving at 7.40 am at 40 kmph.
=> (1 hr 10 min + t)*30 = t*40
=> (7/6 + t)*30 = t*40
=> t = 7/2 or 3.5 hrs i.e. both train meets after 3 hr & 30 min.
Hence distance covered from A is (7/6 + t)*30 or t*40 = 140 km.

Reply Like? Yes | No

Ans.15/16.

Explanation: Because there 2 chances. And 4 digits are to be used. So total no. Of possible outcomes is 2^6=16.
In 2 chances, except 1111, every outcome will have ≥ 1 zero's.
So P(0)= 16-1/16

Suppose earlier consumption of 100 gms of tea and total expenditure was Rs 100 .
With same consumption of 100 gms tea, expenditure after 20% increase in price, will be Rs 120.
As new expenditure is Rs 110 only, total consumption now = 100*110/120 = 91.67 gms

Let before our price is RS100 by increased of 20℅ it goes to 120 . Simply expenditure is also 100 and increase it to 110 by 10℅ .
So, 120 is to 100
Then 110 is to ?? 91.66 : so consumption decrease is 100-91.66== 8.33

Let price of tea and quantity of tea produced = 100P and 100Q respectively,
Then, monthly bill = 10000PQ.
Now,
⇒ Price of tea = 120P (After 20% increase)
⇒ Monthly bill = 11000PQ (after 10% increase)
Then, consumption = 11000PQ/120P = 1100Q/12 = 91.67Q
Reduction in Consumption = (100Q - 91.67Q)/100Q x 100%
= 8.33% or 25/3%

864 units of M contains chemical X ( 480 units) and chemical y ( 384) as their ratio is 5:4 in M.

Latest MBA Aptitude Question SOLUTION: ABCD is a trapezium with AB parallel to CD. AC is perpendicular to BC and BD is perpendicular to AD. If AD=BC=15cm and AB=25cm , find the area of the trapezium ABCD.

Reply Like? Yes | No (1)

(6 years ago)

192 cm^2

BD= Sqrt ( 25^2-15^2) = 20
area of triangle ADB = 20*15/2= 150 sq cm
Height of triangle ADB= 2*150/25= 12 cms
Height for this triangle = equal to the height of trapezium.

so height of trapezium = 12cm.
By calculations, we get
CD=7cm

Area of trapezium =1/2*(AB+CD)*Height

Hence area of ABCD trapezium = (1/2)*(25+7)*12 = 192 sq. cm.

· 2. Average weight of a class of 60 students is 56 kg.
a. With the exit of two students, the average weight of the class reduces by I kg. What is the average weight of the students who leave the class?
b. If the weight of none of the students in the class of 60 was not less than 54 kg, what can be the maximum weight of any student in the class?

Reply Like? Yes | No

(6 years ago)

a. Let an average weight of two students who leave the class be x kg, then
Average weight of remaining 58 students=(60*56 - 2x)/58 = 55
=> 3360 - 2x = 3190 or x=85

b. To get the maximum weight of any of the student in the class, let us consider the remaining 59 students are of minimum weight of 54 kg, and 1 students of maximum weight is of 'x' kg, then
Total weight=59*54 + x = 60*56
=> x=3360 - 3186=174

Q. Two merchants sell, each an article for Rs.1000. If Merchant A computes his profit on cost price, while Merchant B computes his profit on selling price, they end up making profits of 25% respectively. By how much is the profit made by Merchant B greater than that of Merchant A?
Option

Reply Like? Yes | No

(6 years ago)

Given SP = 1000
FOR A,
(SP-CP)/CP * 100 = PP
(1000-CP)/CP *100 = 25
(1000/CP - 1)*100 = 25
1000/CP - 1 = 25/100 = 0.25
1000/CP = 1.25
CP = 1000/1.25 = 800rs
Profit = SP-CP = 1000-800 = 200

FOR B,
(SP-CP)/SP = PP
(1000-CP)/1000 = 25%
1 - CP/1000 = 0.25
CP/1000 = 0.75
CP = 750
Profit = SP-CP = 1000-750 = 250rs

So, profit of B - A = 250-200 = Rs.50/-

By 50rs profile made by Merchant B is greater than that of Merchant A.

12 years ago
explanation: let k years ago
then (4x+k)/(3x+k)=5/3
then x=-2k/3
now present ages become -8k/3 and -2k
according to the given statement i.e, after 4 years this ratio will become 9:7
the ratio becomes
(4-(8k/3))/(4-2k)=9/7
by solving
k=-12

Number of those who studied at least 1 language=n(LUG)=15-3=12
Let Number of those who studied both languages=n(LnG)=x, then n(L)=7-x and n(G)=8-x
As n(LUG)=n(L) + n(G) - n(LnG)
12=(7-x) + (8-x) + x

There are 9 three digit numbers . Each number is reversed and the reversed number is subtracted from the original number. The results were found to have an average of 0. If for each number, hundreds digit is not less than its unit digit , find the average of the hundreds digit of the greatest and least numbers ?

Reply Like? Yes | No

101 is the least 3 digit number to have "hundreds digit not less than unit digit"

Result = 101-101 = 0

999 is the greatest 3 digit number.
Result = 999-999 = 0

Rest 7 numbers take any palindrome numbers like 252, 373, 444, 505, 666, 767, 868
Or any set giving average result zero like:
234, 432, 566, 775, 476, 988, 777

So required answer = (9-1)/2 = 5

1. 10

Let number of students who passed in both=x, then
Students who passed only English=30-x and only maths=20-x
So required difference=Only English - Only Maths = (30-x) - (20-x) = 10
