Which of the following is a multi-user System software (OS)?
The correct answer is B
(64/25)?× (125/512)?-1= 5/8
[(82× 162)/12] - 28 = ?
560 ÷ 14 × 3 – 25 = ?
1(1/2)+ 11(1/3) + 111(1/2) + 1111(1/3) + 11111(1/2) = ?
64.5% of 800 + 36.4% of 1500 = (?)² + 38
30, 39, 66, ? , 174, 255
7(1/5) – 3(1/4) + 8(3/4) = ?
(7/5) × (3/4) × (5/9) × (6/7) × 3112 = ?
The sum of two numbers is 16 and their product is 63. The sum of their reciprocal is equal to:
25% of 300 + √(?) = 35% of 600 - 15% of 300
