Question

Answer

25% of Mr Tan’s salary was $250 more than 1/5 of Mr Lim’s salary. After Mr Tan spent 60% of his salary and Mr Lim spent 1/2 of his salary, Mr Tan had $22 more than Mr Lim, what was Mr Tan’s salary?

Mr Lim’s salary ——- 1u + 1u + 1u + 1u + 1u = 5u
Mr Tan’s salary ——- (1u + 250) + (1u + 250) + (1u + 120) + (1u + 250) = 4u + 1000

(5u/2) + 22 ——- (4u + 1000) x (100% – 60%)
5u + 44 ——- 3.2u + 800
5u – 3.2u = 1.8u ——- 800 – 44 = 756
1u ——- 756/1.8 = 420
4u + 1000 = 4 x 420 + 1000 = 2680

Ans : $2680.
