Q:

A boat can move 5 km/hr in still water. If the river is running at 1 km/hr, it takes it 75 min to move to a place and back. How far is the place?

A) 3 kms	B) 5 kms
C) 6 kms	D) 4 kms

Answer & Explanation Answer: A) 3 kms

Explanation:

Let the place be at a distance of 'd' kms

From the given data,

$\frac{d}{5 - 1} + \frac{d}{5 + 1} = \frac{75}{60} kms \frac{d}{4} + \frac{d}{6} = \frac{5}{4}$

5d/12 = 5/4 => d = 3 kms.

Hence, the place is 3 kms far.

Q:

Simple interest on a certain sum at 7% per annum for 4 years is Rs. 2415. What will be the compound interest on the same principal at 4% per annum in two years?

A) Rs. 704	B) Rs. 854
C) Rs. 893	D) Rs. 914

Answer & Explanation Answer: A) Rs. 704

Explanation:

We know that,

$S . I . = \frac{PTR}{100} \Rightarrow P = \frac{S . I x 100}{T x R} And also, C . I = P [{(1 + \frac{R}{100})}^{n} - 1]$

From given data, P = Rs. 8625

Now, C.I = $8625 [{(1 + \frac{4}{100})}^{2} - 1] = 8625 [{(\frac{26}{25})}^{2} - 1] = 8625 [\frac{676}{625} - 1] = 8625 x \frac{51}{625} C . I = Rs . 703.80$
