Question
There are some assistants and officers in an office, if
12 assistants leave then there are 2 officers for each assistant. After this again 36 officers go and there are 5 assistants for each officer, initially there were assistants.Solution
Assistance denotes by A and officers denote by F. ATQ- 2(A-12) = F         … (1) (A-12) = F/2 (A-12) = (F-36)5 F/2 = (F-36)5 F/10-F = -36 9F = 360 F = 40 Put the value of F in Equation (1) 2A -30 =40 2A =70 A = 35
What will come in the place of question mark (?) in the given expression?
(5/8) × 1600 + (2400 ÷ 25) = ?Â
- What will be come in place of (?) in the given expressions.
45% of 640 + 35% of 320 = ? 5 × 14 + 100 ÷ 4 = 62 + ?
690 ÷ (75% of 460) = ? ÷ (50% of 160)
115 ÷ 23 + 12 × 6 = ? + 16 - 35
Simplify the following expressions and choose the correct option.
(45% of 640) ÷ 8 + (3/4 of 96) = ?
15% of 360 × 20% of ? = 324
- What will come in the place of question mark (?) in the given expression?
(120 - ?) ÷ 2 + 35 = 86 - 11 8 × 9 + ? – 6 × 11 = 12 × 8
[1.45 X 1.45 X 1.45 + 0.55 X 0.55 X 0.55 + 4.785] = ?
