CI = P(1+r/100)^t - P = 6528.24 - 5041 = 1487.24.
compound interest

Question 5

Find the sum of first 14 terms of the AP: First term=4, common difference=2.
S_n = n/2 [2a + (n-1)d] = 14/2*[2*4+(13)*2] = 238.0
sum, arithmetic progression

Question 6

What is 8% of 102?
8% of 102 = (102*8)/100 = 8.16
percentage

Question 7

Calculate simple interest on Rs. 5003 at 2% per annum for 2 years.
Simple Interest = PRT/100 = 200.12.

Question 8

What is the remainder when 173 is divided by 11?
173 modulo 11 = 8.
modular

Question 9

A, B, and C invest Rs. 3133, Rs. 6949, and Rs. 7103 for 8, 10, 7 months respectively. If total profit is Rs. 20000, what is B's share?
Share ratio = 3133×8 : 6949×10 : 7103×7 = 25064 : 69490 : 49721
B's share = (69490 / 144275) × 20000 = 9632.99
