Question

Celine earned $525 more than Abbas each month. They each spent $1250 a month and saved the rest. After 11 months, Celine had $8250 in savings. How much did Abbas earn in a year?

Answer

In 11 months, Celine saved $8250

In 1 month, she saved (8250 ÷ 11) = $750

In 1 month, Abbas saved (750 – 525) = $225

Each month, Abbas earned (225 + 1250) = $1475

In 1 year, Abbas earned (1475 x 12) = $17700

Each month
Celine
earned ——- 1u + 525
spent ——- 1250
saved ——- 1u + 525 – 1250 = 1u – 725

Abbas
earned ——- 1u
spent ——- 1250
saved ——- 1u – 1250

11 x (1u – 725) = 11u – 7975 ——- 8250
1u ——- (8250 + 7975)/11 = 1475
1475 x 12 = 17700

Ans : $17700.

$525 x 11 = $5775

$8250 – $5775 = $2475 (abbas save)

$1250 x 11 = $13750 (abbas spent)

$2475 + $13750 = $16225
