Question
P started a business investing Rs.9000. After 3 months,
Q joined her with the capital of Rs.16000. After another 6 months, R joined them with the capital of Rs.20000. At the end of the year, they made a total profit of Rs.7800. Find the share of R.Solution
P invested her capital for 12 months, Q for 9 months and R for 3 months. So, ratio of their capitals = (9000 × 12):(16000 × 9):(20000 × 3) ⇒ 108000 : 144000 : 60000 ⇒  9 : 12 : 5 Therefore, R’s share = 7800 x (5/26) = Rs.1500

Simplify the following expressions and choose the correct option.
{[(13)² − (7)²] ÷ 12} × 4 = ?
60 % of 640 - 57 × 2 - 1520 / 38 = ?
Solve for the ?
672 ÷ 28 × 24 + 363 – 309 =?
What should come in place of the question mark (?) in the following question?
2 – [6 – {3 + (–4 + 5 + 1) × 8} + 12] = ?
1440 ÷ 12 + 540 ÷ √36 + ? = 180 * 3
116*2/3% of 18600 + 666*2/3% of 1290 = 457*1/7% of 1750 + 555*5/9% of 3150 + ?
40 of 30% of 220 = ? + 790
