Ali the barber shaved 35% of his customers and gave a haircut to 45% of his customers. He charged Rs. 9 for a shave and Rs. 7 for a haircut. If 20% of customers who opted for a shave also had a hair-cut, what were Ali's earnings if he had 160 customers (in Rs.)?
Total customers = 75 Numbers of customers shaved = 160 x (35/100) = 56 Number of customers who got hair cut = 160 x (45/100) = 72 Number of customers who shaved and got hair cut = 160 × (20/100) = 32 ∴ His total income= (56 x 9) + (72 x 7) + (32 × 16) = 1520
25% of 140 + 2 × 8 = ? + 9 × 5
?2 × 25 = 42 × 21 + 172
?% of 320 - 69 = 123
18 × 15 + 86 – 58 =? + 38
3.3 Times 2/27 of 40% of 364=?
(25)² × 4 ÷ 5 + (3)³ + 48=? + 425
4368 + 2158 – 596 - ? = 3421 + 1262
`(450 -: ?)/(2.5 xx 1.2)` = 250
(2 ÷ 3) × (4 ÷ 12) × (? ÷ 10) × 45 × (1 ÷ 5) = (? ÷ 6) + (2 ÷ 5)
Solve the following:
523 + 523 x 523 ÷ 523
