Question
A does 55% of some work in 12 days. Later, with B’s
help, she completes the remaining work in 4 days. In how many days can Be B complete the entire work alone? type-sscSolution
Let total work = 120 units A does 45% of the work=120×45/100=36 Since A does 45% of the work (i.e. 36 units) in 12 days, A = 36/12 = 3 units per day Work left = 120 − 36 = 84 units Let B do x units of work per day. B and A finish the pending work in 4 days. ∴ 4(x + 3) = 84 ∴ 4x = 84 − 12 = 72 i.e. x = 18 units ∴ Time taken by B to complete the work = 120/18 = 6+2/3

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] = ?
