Question
A certain sum of money will be doubled in 2 years at the
rate of simple interest percent per annum is:Solution
SI = (P × R × T)/100 Amount, (A) = P + SI Let P be the principal. SI = 2P – P = P ⇒ P = (P × R × T)/100 ⇒ P = (P × R × 2)/100 ⇒ R = 100/2 = 50%

- 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.)
79.99% of (84.89 × 5.99) - (3.89)2 × 21.87 = ?
(44.85% of 639.79 + 3/8 of 480.23) × (√63.84 – 19.99% of 499.71) = ?

Solve the following expression and calculate the approximate value.
398% of 388 + 129% of 323.89 – 430.93
35.05% of 200.05 – 20.15% of 99.99 × 3.02 = ?
? 2 + (39.99 × 10.99 + 7.01) - (39.99 × 2.99 2 + 21.99) = 21.99 × 23.01
Direction: Solve the following expression and calculate the approximate value.
(5.78 + 3.12)² + 8.2² + 2 × 8.1 × (5.9 + 3.2)
...[(2/3 of 599.77) + (39.69% of 450.14)] ÷ [(5/8 of 399.79) - √120.91] = ?
