Question
The population of a town increased to 13,520 in 2022 at
a rate of 4% per annum. Find the population of that town in 2020.Solution
ATQ. Let P be the population of town in the year 2020 population in the year 2022 = A = 13,520 (given) Using the formula of CI-

436 × 794 – 68210 =? + 85730
520% of 360 β 12% of 400 = ? x 4
236.23 - 653.23 + 696.23 = ?
{(? Γ 15) + (? Γ 45)} β 120 = 360
What will come in the place of question mark (?) in the given expression?
(437 + ? - 167) x 2.5 = 875800 + 900 X (3)-2 - ? = 25 X 60 Γ· 2Β
37% of 810 – 32% of 460.5 = ?
- What will come in place of (?) in the given expression.
(β of 450) β (β of 300) = ? 1024 Γ· 16 + 800 Γ· β64 + ? = 200 * 2
