Question
Some amount out of Rs. 12000 was lent out at 10% per
annum and the rest amount @ 16% per annum and thus in 5 years the total interest from both the amount collected was Rs. 7200. What is the amount which was lent out at 10% per annum?Solution
Overall interest(SI) = (12000×R×5)/100 = 7200 or R = 12% Using allegation method 
Money lent @ 10% = 2/(2+1) × 12000 = 2/3 × 12000 = Rs. 8000

- 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.)
Find the approximate value of Question mark(?). There is no requirement to find the exact value.
? = 599.77 – 14.08 × 20.11 + (12.93)²
(124.99)² = ?
(29.97%) of 9840 + ? + (45.17% of 1240) = (31.99% of 11750)
10.10% of 999.99 + 14.14 × 21.21 - 250.25 = ?
(29.98% of 9840) + ? + (19.899% of 8490) = 7560
