Question
A started a business with an investment of Rs.18000.
After few months B joined him with an investment of Rs.22500. If at the end of the year, they share the profit in the ratio of (A:B) 5:6, then find after how much time B joined the business?Solution
Let B invested for ‘m’ months. According to the question, => (18000 x 12)/(22500 x m) = 6/5 => m = 8 months So, the required time = 12 – 8 = 4 months

- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
142.07 + 21.89 – (128.12 ÷ 7.81 – 12.09 × 6.98) = ?
26.23 × 31.82 + 44.8% of 1200 + ? = 1520
4650.12 ÷ √8648.88 + √27.08 * √1727.85 = ? – 609.10 ÷ 87.07                     Â
...(20.98 ÷ 2.91) + (15.12 – 5.96) = ?Â
