Question

What value will replace the question mark in each of the following equations ?

(i) ? - 1936248 = 1635773

(ii) 8597 - ? = 7429 - 4358

Answer 1

(i) Let x - 1936248 = 1635773.

Then, x = 1635773 + 1936248 =3572021.

(ii) Let 8597 - x = 7429 - 4358.

Then, x = (8597 + 4358) - 7429

= 12955 - 7429

= 5526.
