45896 + A = 96023 + B - B
A = 50127

QUESTION: 3

You have to replace the digit 8 in the numbers 5487952 and 798556 such that their sum becomes 6231508. By which one of the following digits would you like to replace 8?

Solution:


We need to replace 8 by some digit to get Sum 6231508
6286508 - 6231508 = 55000
=> Sum would be reduced by 55000 Currently Values of 8 are 80000  & 8000
=> 88000 - 55000 = 33000 = 30000 + 3000
Hence 8 should be replaced by 3.

2+75-12

77-12 = 65

QUESTION: 7

If x = 956, y = 877and x − y = z. Find the value of x + y + z.
