Tushar belwal 2 years ago

If u add water then amount of milk remains same i.e
Initial amount of Milk = 95% × 40 = 38
Final amount of milk = 90% × (x) =38
=> x=42+2/9
Amount of water added = 42+2/9 -40 = 2+2/9

the new average is ?

aman aditya 2 years ago

Sum =2000
Average =50
So, K =2000/50 =40 (Average = Sum of observations / Number of observations)
Now 91 is added so sum becomes 2000+ 91= 2091
New average = 2091 /(40 +1) = 51 Ans

Rajkumar Madanoli 2 years ago

50K=2000 so, K Numbers=40. Now 91 is to be added.
New average = 50(Average)+41(Extra and this extra is distributed among all the numbers , as their will be 41 number after including 91.)

Q The length of a rectangle is decreased by 10% but the area remains the same. Then, percentage
increase in the breadth of the rectangle is ? plz explain

Reply Like? Yes (1) | No

aman aditya 2 years ago

Let Suppose,
Length = 10
Breadh = 18
So, Area = 18 * 10 = 180
Now length is decreased by 10% so new length = 9
Area = l * b
180 = 9 * b
b =20

Difference in breadth = (20 - 18) = 2
% change = (2 * 100)/18 = 11.1 % Ans

lcm of 4,5,6=60
therefore all multiple of 60 will be divisible by 4,5,6.
so the exactly 6 number is divsible by 4,5,6

Reply Like? Yes (1) | No

SunNy Yadav 3 years ago

Let the side of square be .. = 10
Then area of square =>
10×10 = 100
Now,
One side is increased by 30%,
10×130/100 = 13
Let other side be decreased by x ,
So area of square
13×(10-x) = 100
130-13x = 100
x = 30/13
So the other side decreased by 30/13 %

Rishu 3 years ago

40/42

let distance be d and time interval be t

distance covered by tom in one jump=d/7
distance covered by jerry in one jump=d/5

time taken by tom for one jump=t/8
time taken by jerry for one jump=t/6

speed=distance/time

toms speed=(distance covered in one jump)/(time taken for one jump)
=(d/7)/(t/8)=8d/7t
similarly,
jerrys speed=(d/5)/(t/6)=6d/5t

toms speed/jerrys speed=(8d/7t)/(6d/5t)=40/42
