Question
A man deposited 40% of his salary to a bank which offers
compound interest at the rate of 10% p.a. If the interest earned by him from the bank after 2 years is Rs. 2520, find the monthly expenditure of the man which is 52% of his monthly salary.ΒSolution
Let the amount of money deposited in the bank be Rs. βxβ. So, x Γ [(1.1)2 β 1] = 2520 0.21x = 2520, x = 12000 So, monthly income of man = 12000/0.4 = Rs. 30000 Required monthly expenditure of man = 52% of 30000 = Rs. 15600
2*1/3 + 22*1/3 + 222*1/3 + 2222*1/2 + 22222*1/2 = ?
(8.6 Γ 8.6 + 4.8 Γ 4.8 + 17.2 Γ 4.8) Γ· (8.62 β 4.82 ) = ? Γ· 19
30 of 20 - 40 + 182 - 23 Γ ? = 83Β
