Question
A sum when invested at simple interest of 10% p.a.
amounts to Rs. 26,000 after 3 years. If the same sum was invested at simple interest of 8% p.a. for 5 years, then what would be the interest earned?Solution
Let the sum invested be Rs. 'P' Simple interest = (Sum X Rate of interest X time period in years) ÷ 100 ATQ: 26000 - P = (P X 10 X 3) ÷ 100 Or, 26000 - P = 0.3P So, 26000 = 1.3P So, P = (26000/1.3) = 20,000 So, required interest = (20000 X 8 X 5) ÷ 100 = Rs. 8,000
1519.98 ÷ 50.48 × 15.12 = ? × 4.16
Solve the following expression and calculate the approximate value.
14.96% of 120.03 - 107.99 + 88.93% of 199.87 = ?
- 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
