Question
A and B started a retail store with initial investments
in the ratio 7:8 and their annual profits were in the ratio 2:3. If A invested the money for 8 months, then for how many months did B invest his money?ÂSolution
Suppose A invested Rs. 7x for 8 months and B invested 8x for y months then, ⇒  (7x × 8)/(8x × y) = 2/3 ⇒  y = (56x × 3)/(8x × 2) ⇒  y = 168x/16x ⇒  y = 10.5
Calculate the value of x2,  if [(8 + 62) ÷ 4 of x + 2.5 × 5 = 42 + 20% of 10].
√ (12+√ (12+√ (12+ ⋯ ∞ ))Â
648 ÷ 36 × 49 – 1012 + 847 = ?
1024 ÷ 16 + 800 ÷ √64 + ? = 200 * 2
12.232 + 29.98% of 539.99 = ? × 5.99
- What will come in place of (?) in the given expression.
(14)² – (12)² = ? 1/6+ 999*53/54 ×9 = ?
33 × 5 - ?% of 250 = 62 - 6
323 × 15 + (?)² = 4989
13 X √? + 256 ÷ 4 = 30% of 900 - 50
