Two fill pipes A and B can fill a tank in 30 and 20 hours respectively. Pipe B alone
is kept open for half the time and both pipes are kept open for the remaining time.
In how many hours, will the tank be completely full?

15 hrs

Let the total time taken be 'x' hrs.
Then, for x/2 hrs pipe B fills at 1/20 per hr and for remaining x/2 hrs both pipes A & B fills at (1/30 + 1/20) per hr.
(x/2)*(1/20) + (x/2)*(1/30 + 1/20) = 1
(x/2)*(8/60) = 1

Let C takes 'x' days, then A takes 3x days and B takes 3x/2.
1 day work of A , B & C = 1/3x + 1/(3x/2)+ 1/x = 1/2
=> x=4
Therefore, A takes 12 days and B takes 6 days to do the work alone.

1.2/3rd of the balls in a bag are blue, the rest are pink. if 5/9th of the blue balls
and 7/8th of the pink balls are defective, find the total number of balls in the bag
given that the number of non defective balls is 146?

Reply Like? Yes | No

(3 Months ago)

432

Let total balls be x. Blue=2x/3, Pink=x/3
Defective balls = (5/9)*(2x/3) + (7/8)*(x/3) = 143x/216
Non defective balls = x - 143x/216 = 73x/216
Given non defective balls are 146, so 73x/216 = 146 => x=432

Like? Yes | No

(3 Months ago)

Let total balls in the beg are x
Then Blue balls in the beg are = 2x/3
Pink balls in the beg are = 1-2x/3=x/3
Defective blue balls= 5/9 (2x/3)
Defective pink balls= 7/8 (x/3)
Total Defective balls in the beg are= 143x/216
Hence total non defective balls in the beg are = x-143x/216=73x/216
Given that total defective balls in the beg are 146
Hence 73x/216=146
i.e. X= 432 Balls

Like? Yes | No

(3 Months ago)

Let the total numbers of the ball in a bag be x.

Blue balls = 2/3 of x

Pink ball = x - 2x/3

= x/3

Now,

Defective Blue balls = 5/9 of (2/3 of x)

= 5/9 × 2/3 × x

= 10/27 × x

Defective Pink balls = 7/8 of x/3

= 7x/24

Now, Defective Blue and Pink balls = 146

10x/27 + 7x/24 = 146

(80x + 63x)/216 = 146

∴ 143x = 146 × 216

x = 220.53

= 221 balls.

Raman, Naman and Aman are roommates and were given a job to clean their room on Sundays. The job was easy, but they made it complicated. Sometimes they did it in pairs, sometimes individually, sometimes they did it all together. At the end of the month, a mathematician had following observations:
1. Aman needed 1 hour less than Raman to complete the work.
2. When they all worked together, they required 60 minutes to do complete job.
3. When Raman and Naman started working together and Raman left after 1 hour, then Naman had to work further for 3 more hours to complete the job.
The mathematician wants you to calculate how much work does Aman do per hour?

The average temperature of Monday, Tuesday and Wednesday were 37°C and on Tuesday, Wednesday and Thursday was 34°C. If the temperature on Thursday was 4/5 th of that of Monday, then what was the temperature on Thursday?
a) 36 °C

Reply Like? Yes | No (1)

(4 Months ago)

Ans: 36°C

Mon+Tue+Wed=3x37=111 ---(i) and Tue+Wed+Thu=3x34=102 ---(ii)
Subtracting (ii) from (i), Mon - Thu=9 ---(iii)
Given, Thu=(4/5)xMon => Mon=(5/4)xThu
Substituting this value of Mon in (iii), (5/4)xThu - Thu=9
Thu=36
Therefore, temperature on Thursday was 36 °C.

Find unit digit of x raised to power y
Given two numbers x and y, find unit digit of xy.
Method 1 (Simple) Compute value of xy and find its last digit. This method causes overflow for slightly larger values of x and y.

Method 2 (Efficient)
1) Find last digit of x.
2) Compute x^y under modulo 10 and return its value.

// Efficient C++ program to
// find unit digit of x^y.
#include

using namespace std;

// Returns unit digit of x
// raised to power y

int unitDigitXRaisedY(int x, int y)
{

// Initialize result as 1 to

// handle case when y is 0.

int res = 1;

// One by one multiply with x

// mod 10 to avoid overflow.

for (int i = 0; i < y; i++)

res = (res * x) % 10;

return res;
