How much does a watch loss per day, if its hands coincide every 60 minutes?
55 minutes spaces are covered in 60 minutes. 60 minutes spaces are covered in [(60× 60)/55] = 65 5/11 minutes Loss in 60 minutes (65 5/11 - 60) minutes = 5 5/11 minutes or 60/11 minutes Loss in 24 hours = 60/11× 1/60× 24× 60 = 1440/11 or 130 10/11 minutes.
[4(2/3) + 5(1/6)] × 45% of 240 = ?
The value of ((0.27)2-(0.13)2) / (0.27 + 0.13) is:
Simplify-
x + 3(y + x – 2) – (x + y).
125% of 80 – 6 × 4 = ? × 13 – 54
144 (1/2) × 14 – 28 = 7 × ?
34 × 5 × 2 ÷ 6 + 7 × 5 + 13 = (?)× 6 – 754
15% of 2400 + (√ 484 – √ 256) = ?
375% of 320 - 80% of 40 ÷ √256 = ?
√1444 + √729 – √2116 = ?
