CA Foundation Maths Question Paper Jan 26 With Solution - 5


1. If an amount is compounded annually so that it tripled itself in 4 years, then the annual rate of interest is (Given that 3^(1/4) = 1.316)
(A) 13.6%
(B) 31.1%
(C) 31.6%
(D) 11.3%

Solution: (C) 31.6%

Choice ‘C’ is correct as—

Given that the amount triples in 4 years under compound interest.
So,
(1 + r)⁴ = 3
Taking fourth root:
1 + r = 3¹ᐟ⁴ = 1.316
r = 1.316 − 1 = 0.316 = 31.6% per annum

2. Bank B provides loans at 15% per annum compound interest. If Mr. XYZ borrowed ₹ 3,200 for 2 years from Bank B, then how much interest must Mr. XYZ pay to his bank?
(A) ₹ 400
(B) ₹ 960
(C) ₹ 4,232
(D) ₹ 1,032

Solution: (D) ₹ 1,032

Choice ‘D’ is correct as—

Principal = ₹ 3,200
Rate = 15% p.a., Time = 2 years

Amount = 3,200 × (1.15)²
= 3,200 × 1.3225
= ₹ 4,232

Interest = 4,232 − 3,200 = ₹ 1,032

3. If a sum double itself in 8 years, then in how many years it will becomes four times, assuming that the simple interest is calculated.

"Koncept perfectly justifies what it sounds, i.e, your concepts are meant to be cleared if you are a Konceptian. My experience with Koncept was amazing. The most striking experience that I went through was the the way Yash sir and Ruchika ma'am taught us in the lectures, making it very interesting and lucid. Another great feature of Koncept is that you get mentor calls which I think drives you to stay motivated and be disciplined. And of course it goes without saying that Yash sir has always been like a friend to me, giving me genuine guidance whenever I was in need. So once again I want to thank Koncept Education for all their efforts."
