Question : A sum of Rs. 400 becomes Rs. 448 at simple interest in 2 years. In how many years will the sum of Rs. 550 amounts to Rs. 682 at the same rate?

Option 1: 2 years

Option 2: 3 years

Option 3: 3.5 years

Option 4: 4 years

Team Careers360 21st Jan, 2024

Correct Answer: 4 years


Solution : Interest for 2 years = Rs. (448 – 400) = Rs. 48
i.e. 1 year interest = $\frac{48}{2}$
1 year interest = Rs. 24
We know Rate of interest = $\frac{\text{Simple interest} \times 100}{\text{Principal × Time}} = \frac{48 \times 100}{400 \times 2} = 6$%

Question : Comprehension:

Read the passage and answer the questions that follow.

The drainage systems of India are mainly controlled by the broad relief features of the subcontinent. Accordingly, the Indian rivers are divided into two major groups: the Himalayan rivers; and the Peninsular rivers.
 

Apart from originating from the two major physiographic regions of India, the Himalayan and the Peninsular rivers are different from each other in many ways. Most of the Himalayan rivers are perennial. It means that they have water throughout the year. These rivers receive water from rain as well as from melted snow from the lofty mountains. The major Himalayan rivers are the Indus, the Ganga, and the Brahmaputra. These rivers are long and are joined by many large and important tributaries. A river along with its tributaries may be called a river system. The two major Himalayan rivers, the Indus and the Brahmaputra originate from the north of the mountain ranges. They cut through the mountains making gorges in the upper course. The perennial Himalayan rivers have long courses from their source to the sea. They perform intensive erosional activity in their upper courses and carry huge loads of silt and sand with their swift current. In the middle and the lower courses, these rivers form meanders, oxbow lakes, levees, and many other depositional features in their floodplains as their speed slackens. They also have well-developed deltas.
 

A large number of the Peninsular rivers like the Godavari, Kaveri, and Krishna are seasonal, as their flow is dependent on rainfall. During the dry season when it doesn’t rain, even the large rivers have reduced flow of water in their channels. The Peninsular rivers have shorter and shallower courses as compared to their Himalayan counterparts. However, some of them originate in the central highlands and flow towards the west. Most of the rivers of peninsular India originate in the Western Ghats and flow towards the Bay of Bengal.

Option 1: 12 minutes 20 seconds

Option 2: 13 minutes

Option 3: 13 minutes 40 seconds

Option 4: 14 minutes 24 seconds

Team Careers360 20th Jan, 2024

Correct Answer: 13 minutes 40 seconds


Solution :
Let, $CD$ = 10 units
In $\Delta ABC$,
$\tan 45^{\circ} = \frac{AB}{BC}$
$\Rightarrow BC = AB \quad................(1)$
In $\Delta ABD$,
$\tan 60^{\circ} = \frac{AB}{BD}$
$\Rightarrow \sqrt{3} = \frac{AB}{BD}$
$\Rightarrow AB = \sqrt{3} BD$
$\Rightarrow BC = \sqrt{3} BD \quad [\text{using (1)}]$
$\Rightarrow
