Question
8 workers working for 8 days make 8 motor cycles. Then
how many motor cycles would be made by 4 workers if they work for 4 days? Assume equal efficiency of each worker.Solution
ATQ, If 8 workers make 8 motorcycles in 8 days, each worker makes 1 motorcycle in 8 days. Now, let’s see how many motorcycles 4 workers can make in 4 days: 1 worker makes 1/8 of a motorcycle in 1 day. So, 1 worker makes 4/8 (which is 1/2) of a motorcycle in 4 days. If 1 worker makes 1/2 a motorcycle in 4 days, 4 workers will make 4 times as much in 4 days, because there are 4 of them: 4 workers make 4 x (1/2) = 2 motorcycles in 4 days.
1885 ÷ 64.98 + 7.29 + ? = 69.09
212 + 14 × 23 – 28 × 15 = ? Â
(22² × 8²) ÷ (92.4 ÷ 4.2) =? × 32
567-4824 ÷ 134 =? × 9
Determine the value of 'p' in the expression.
28 ÷ 22p + 1 = 43Â
What will come in place of (?) in the given expression.
(15) ² - (13) ² = ?? = 6.25% of 240 + 25 2 + 17 2 – 16 × 17
35% of 840 + 162 = ? – 25% × 300
(7/5) × (3/4) × (5/9) × (6/7) × 3112 = ?
1024 ÷ 16 + 800 ÷ √64 + ? = 200 * 2
