Question
Anita and Rohan each invested a sum of ₹12,000 for 2.5
years at 20% compound interest per annum. However, while for Anita the interest was compounded annually, for Rohan it was compounded quarterly. How much more will Rohan receive as interest compared to Anita at the end of the 2.5 years?Solution
For Anita (compounded annually): A = ₹12,000 (1 + 20/100)2.5 = ₹12,000 × (6/5)2.5 = ₹20,953.92 Interest = A – P =20953.92-12000 = ₹8,953.92 For Rohan (compounded quarterly): Rate per quarter = 20 × 3/12 = 5% Time = 2.5 × 4 = 10 periods A = ₹12,000 (1 + 5/100)10 =12,000 × (21/20)10 = ₹21,331.02 Interest = A – P =21331.02-12000 = ₹9,331.02 Difference in interest = 9,331.02 - 8,953.92 = ₹377.10
212 + 14 × 23 – 28 × 15 = ?
382 + 482 + 572 = ? - (81 x 49)
What will come in place of (?) in the given expression.
(18 + 24 ÷ 6) × 2 - 5 = ?If x - 1/x = 9, then the value of x² + 1/ x² is:
- What will come in place of (?), in the given expression.
3² × 5 + 2³ × 4 = ? Calculate the value of x2, if [(8 + 62) ÷ 4 of x + 2.5 × 5 = 42 + 20% of 10].
3/7 of 686 + 133(1/3)% of 33 – 69 =?
- Find the simplified form of the following expression:
128 - 85 of 2 + 26 X 4 What value should come in place of (?) question mark in the given expression.
(5/8 of 256) + (2/5 of 125) − 14 = ?
