Question
Simple interest earned on an amount of Rs. 1000 at rate
of R% per annum after 4 years is Rs. 280. Find the simple interest earned on an amount of Rs. 1500 at rate of (R + 4)% per annum after 3 yearsSolution
According to question, 280 = 1000 × R% × 4 R = 7 Therefore, required interest = 1500 × (7 + 4)% × 3 = Rs. 495
?2 + 114 - 48 ÷ 2 × 5 = 163
What will come in the place of question mark (?) in the given expression?
√1936 + (84 ÷ 2 × 1.5) – 35² + 18² = ?
19 × ? = 361 ÷ 19
What will come in the place of question mark (?) in the given expression?
{180 + (2250/15)} ÷ 11 = ?2 + 14
182 + 10 × 12 - ? = 312
- Calculate the value of x if x% of 400 plus {800 ÷ x of 8} × 4 is equal to 88
Solve the following:
523 + 523 x 523 ÷ 523
(630 ÷ 35) × 2 + 144 = ? × 2
 {(481 + 426) 2 - 4 × 481 × 426} = ?
(42% of 1500 + 170) ÷ 4 = ?2 - 52Â
