Question
A certain sum at certain rate % per annum simple
interest becomes Rs 6300 in 2 years and Rs 6750 in 5 years. The principal and rate of interest are -Solution
According to the given information, interest of 3 years for that the given sum = 6750 – 6300 = 450 Therefore, the interest of 1 year for the same sum = 450/3 = Rs 150 Hence, required sum = 6300 – (150 × 2) = 6000 Whereas, rate of interest = (150 × 100)/(6000 × 1) = 2.5%

Determine the simplified value of the expression: 12 × 15 - 20 + 15 + 12 - 18 + 3 × 4 + 18.
12.5% of 45 % of 480 + 957/29 = ? -14 × 15
22 + 60 × 3 ÷ 12 = ?
(√121 + √196) × 7 =? × 5
Solve the following:
240 ÷ 4 × 512 ÷ 8
45% of 360 - 160 + ? = √324
[192 ÷ 6 × 5] ÷ (? + 3) = 20
What will come in place of (?) in the given expression.
{(60% of 250) + √144} ÷ (3² - 4) = ?1.25 × 36 + 2.75 × 40 = ? × 3.1
60 % of 640 - 57 × 2 - 1520 / 38 = ?
