Q:

A salesman gets commission on total sales at 9%. If the sale is exceeded Rs.10,000 he gets an additional commission as bonus of 3% on the excess of sales over Rs.10,000. If he gets total commission of Rs.1380, then the bonus he received is:

A) Rs.180	B) Rs.120
C) Rs.480	D) data insufficient

Answer & Explanation Answer: B) Rs.120

Commission up to 10000 = $\frac{10000 x 9}{100}$ = 900

Again after 10000,

Commission : Bonus

9 : 3

3x : x

Therefore, Bonus = $(1380 - 900) \times \frac{1}{4} = R s . 120$
