2x + 3x + 4x = 93-30

9x =63

x=7

4x =28

Masud's age=38

 

What will be the least number which when doubled will be exactly divisible by 12,18,21 and 30

the number is 630

 

A train 80 meters long is running at a speed of 78km/hr. If it crosses a tunnel in 1 minute, then the length of the tunnel is:

tunnel is x meter

in 1 min the train crosses x + 800 miter

speed =78km/hr=78000m/60min = 1300m/min

x+800 =1300

x=500

 

If 4 A's Capital = 6 B's Capital = 10 C's Capital, then out of a profit of 4650, C will get

 

4a=6b=10c=k

then a=k/4, b=k/6,c=k/10

a:b:c= k/4 : k/6 : k/10 = 15:10:6

C gets 4650* 6/31 = 900

 

How many times in a day, are the hands of a clock in straight line but opposite in direction?

 

The hands of a clock point in opposite directions (in the same straight line) 11 timesin every 12 hours. (Because between 5 and 7 they point in opposite directions at 6 o'clcok only). So, in a day, the hands point in the opposite directions 22 times.

 

Two numbers A and B are such that the sum of 5%of A and 4% of B is two-third of the sum of 6% of A and 8% of B. Find the ratio of A :B

 

5% of A + 4% of B =2 /3(6% of A + 8% of B)

A : B =4:3

 

If the number 5*2 is divisible by 6 the * =?

As we can see it is an even number, so to be divisible by 6 it needs to be divisible by 3.

If the sum of the digits of a number is divisible by 3, then the total number is divisible by 3.

So putting 2 in the place of * the sum of the digit will be 5+2+2 = 9, which is divisible by 3

 

3 pumps, working 8 hours a day can empty a tank in 2 days. How many hours a day must 4 pumps work to empty the tank in 1 day.

A student was asked to find the arithmetic mean of the numbers 3,11,7,9,15,13,8,19,17,17,21, 14 and x. He found the mean to be 12. What should be the number in place of x?

 

Clearly, we have (3 + 11 + 7 + 9 + 15 + 13 + 8 + 19 + 17 + 21 + 14 + x) / 12 = 12.

or  137 + x = 144

or x = 144 - 137 = 7.

How many days are there in x weeks x days?
