Question
A car driver’s income consist of his salary and
tips. During one week his tips were 5/4 of his salary. What portion of his total income came from tips?Solution
Let salary of car drivers be = x Then his tips = x× 5/4 = 5x/4 Total income = x+ 5x/4 = 9x/4 Portion of income come from tips = (5x/4)/(9x/4) = 5/9
32% of 4080 + 24% of 540 = ? % of 3200
350% of (450 / 1.5) = ?% of 4200Â Â
Simplify the following expressionÂ
Â
25% of 60 × 15% of 120 = 30% of (?)
?/4 ÷ 9/? = 15% of 800 + `1(2/3)` × `1(1/5)` × 1/2
522 + 160% of 80 - 130 = ? X 13Â
√196 + (0.25 × 144) + 19 = ? + 72
192.251 + 326.233 + 125.021 + 19.273 = ?
?% of 18% of 2600 = 234
535 + ? × 27 - 22 × 20 = 230Â
