Question
The difference between compound interest and simple
interest at the same rate for Rs. 3200 for 2 years is Rs. 128. The rate of interest per annum is:Solution
When difference is given between SI and CI for 2 years, then the formula is: CI – SI = P (R/100)2 According to the question, => 128 = 3200 (R/100)2 => R2 = (128 × 10000)/3200 => R = 20%
?% of 320 = 40% of 40 × 5
(22² × 8²) ÷ (92.4 ÷ 4.2) =? × 32
42% of 400 + 38% of 800 + ?2 = 728
What will come in place of (?) in the given expression.
{(60% of 250) + √144} ÷ (3² - 4) = ?- What will come in place of (?) in the given expression.
√324 + √121 – √49 = ? Determine the simplified value of following expression:
0.998 + 0.882 + 0.12Â
√225 + 27 × 10 + ? = 320
(26)2 = {(20% of 40% of 18200) ÷ ?} × 1664 ÷ 128Â
(2 ÷ 3) × (4 ÷ 12) × (? ÷ 10) × 45 × (1 ÷ 5) = (? ÷ 6) + (2 ÷ 5)
What is the value of 143 + 163 + 183 + … + 303?
