What least number must be subtracted from 2641 so that the remainder left, when divided by 10,15 and 25, is 7 in each case ?

Answer»

84



LCM of 10, 15, 25 = 150
When we drive 2641 by 150 the REMAINDER is 91.
But the remainder should be 7.
So, the number to be subtracted from 2641 is 91 - 7 = 84.
