20% of 350 = 0.2 × 350 = 70.
The parts add to 5. Girls = 2/5 × 30 = 12.
Speed = distance ÷ time = 240 ÷ 4 = 60.
The sum is 100, and 100 ÷ 4 = 25.
Profit is 100 on a cost of 500, so 100/500 × 100 = 20%.
The daily work is 1/10 + 1/15 = 1/6, so they take 6 days.
Ali > Bilal > Chand, so Chand is the shortest.
The distance is √(5² + 5²) = √50, which is about 7.07 km.
10 days is 1 week and 3 days, and 3 days after Wednesday is Saturday.
Simple interest = 2,000 × 10 × 2 ÷ 100 = 400.
Selling price is 90 percent of cost: cost = 90 / 0.9 = 100.
36 x 36 = 1,296.
Work = 6 x 12 = 72 man days. 72 / 9 = 8 days.
0.15 x 240 = 36.
Total was 100 and is now 72, so the removed number is 28.
150 / 2.5 = 60.
The parts total 8, so one part is 8 and the larger number is 5 x 8 = 40.
The rise is 50 on 200, which is 25 percent.
12 = 2² x 3 and 18 = 2 x 3², so LCM = 2² x 3² = 36.
The minute hand is at 90° and the hour hand at 97.5°, so the angle is 7.5°.
4 x 7 + 3 = 31.
Interest is 600 in 2 years, so 300 a year, which is 6 percent of 5,000.
