Question
In a factory, there are 3 machines. Machine A completes
a task in 8 days, Machine B completes it in 12 days, and Machine C completes it in 15 days. If all machines are working together, how long will they take to complete the task?Solution
Rate of work of A = 1/8, B = 1/12, C = 1/15 Combined rate of work = 1/8 + 1/12 + 1/15 LCM of 8, 12, and 15 = 120 Combined rate = (15 + 10 + 8)/120 = 33/120 Time taken = 40/11 days Correct Option: a
((67)32 × (67)-18 / ? = (67)⁸
18(1/3) + 9(2/3) – 10(1/3) = 1(2/3) + ?
(342 – 20% of 5280) = ? ÷ 3
24% of 35% of (5/8) of 2400 = ?
What will come in place of (?) in the given expression.
40% of (120 + 80) + 25% of 160 = ?What will come in the place of question mark (?) in the given expression?
? = (27 × 13) – 26% of (412 – 92 )
What is the value of (152+82) ÷17
12 % of 72 × 25 – (x ÷ 20) × (16 ÷ 24) × 36 + 1/5 × x = (4 ÷ 12) × 36 ÷ 1/4
What will come in the place of question mark (?) in the given expression?
24% of 350 + 246 = ? + 50 × 2.5
46.2 × 8.4 × 3 + ? = 1200
