Question

find the smallest number which is when increased by 19 exaclty divisible by 24,48,96 and 144​

Answer 1

Answer:

The smallest number which when increased by 20 is exactly divisible by 90 and 144 is given as -

First of all let us find a number which is exactly divisible by 90 and 144 like -

               90*8=720                         and                          144*5=720

Now,

To get  smallest number which when increased by 20 is exactly divisible by 90 and 144 do  

                          <                720 - 20 = 700                >

so, 700 is the smallest no. which when increased by 20 is exactly divisible by 90 and 144.
