Sohan invested Rs 45000 in company C for three years at simple interest and then in company D for three years at compound interest. What is the difference between the amount he will get after six years and amount he invested initially?

Correct

Answer- 2) 13344.3
Explanation-
Amount Sohan will receive after three years from company C = 112/100 × 45000 = Rs 50400
Amount Sohan will receive after further three years after investing in company D = 115.7625/100 × 50400 = Rs 58344.3 (the interest rate will be 5% in this case since the amount in more than Rs 50000)
Required difference = 58344.3 – 45000 = Rs 13344.3

Incorrect

Answer- 2) 13344.3
Explanation-
Amount Sohan will receive after three years from company C = 112/100 × 45000 = Rs 50400
Amount Sohan will receive after further three years after investing in company D = 115.7625/100 × 50400 = Rs 58344.3 (the interest rate will be 5% in this case since the amount in more than Rs 50000)
Required difference = 58344.3 – 45000 = Rs 13344.3

Directions (Q1-5). Five companies A, B, C, D and E offer different interest rates for different amount of investments as shown by the following table. Read it carefully and answers the following questions.

An amount of Rs 19700 was invested in company D for three years at compound interest (the amount is transferred to higher interest rate scheme when it crosses Rs 20000). What is the total interest earned on the amount?

Correct

Answer- 4) Rs 2458.8349
Explanation-
Amount after 1 year = 19700 + 3.2% of 19700 = 19700 + 630.4 = Rs 20330.4
Amount after 2 years = 20330.4 + 4.4% of 20330.4 = 20330.4 + 894.5376 = Rs 21224.9376
Amount after 3 years = 21224.9376 + 4.4% of 21224.9376 = 21224.9376 + 933.897254 = Rs 22158.8349
Compound interest = 22158.8349 – 19700 = Rs 2458.8349

Incorrect

Answer- 4) Rs 2458.8349
Explanation-
Amount after 1 year = 19700 + 3.2% of 19700 = 19700 + 630.4 = Rs 20330.4
Amount after 2 years = 20330.4 + 4.4% of 20330.4 = 20330.4 + 894.5376 = Rs 21224.9376
Amount after 3 years = 21224.9376 + 4.4% of 21224.9376 = 21224.9376 + 933.897254 = Rs 22158.8349
Compound interest = 22158.8349 – 19700 = Rs 2458.8349

An amount of more than 1 lakh was invested in company E at compound interest for two years. What was the amount invested if the interest earned is Rs 20790.77?

Directions (Q1-5). Five companies A, B, C, D and E offer different interest rates for different amount of investments as shown by the following table. Read it carefully and answers the following questions.

An amount of more than Rs 50000 and less than Rs 1 lakh was invested in company D for 1 year. In one year it became more than Rs 1 lakh. It was then invested in company E for two years at simple interest. After three years it amounts to Rs 116323.2. What was the amount invested initially?

Correct

Answer- 3) Rs 96000
Explanation-
Let the amount invested is Rs x.
Amount after 1 year = x + 5% of x = 1.05x
Amount after further two years = 1.05x + (2 × 7.7)% of 1.05x = 1.05x + 0.1617x = 1.2117x
According to question,
1.2117x = 116323.2
x = 116323.2/1.2117 = Rs 96000

Incorrect

Answer- 3) Rs 96000
Explanation-
Let the amount invested is Rs x.
Amount after 1 year = x + 5% of x = 1.05x
Amount after further two years = 1.05x + (2 × 7.7)% of 1.05x = 1.05x + 0.1617x = 1.2117x
According to question,
1.2117x = 116323.2
x = 116323.2/1.2117 = Rs 96000

The following pie chart gives information about the distance travelled on each day in percentage. Read it carefully and answer the given questions.

On Monday, a truck starts from the same place where Robin is supposed to reach at which Robin is supposed to reach on that day. It moves towards Robin at the speed of 24 km/h at the same time when Robin starts his journey. What is the speed of Robin’s car for the day if they met after 4 hours?

Correct

Answer- 5) 84 km/h
Explanation-
Distance travelled by Robin on Monday = 24% of 1800 = 432 km
Let the speed of Robin’s car on Monday is x km/h
According to question, we have,
432/ (24 + x) = 4
432 = 96 + 4x
4x = 432 – 96 = 336
x = 336/4 = 84 km/h

Incorrect

Answer- 5) 84 km/h
Explanation-
Distance travelled by Robin on Monday = 24% of 1800 = 432 km
Let the speed of Robin’s car on Monday is x km/h
According to question, we have,
432/ (24 + x) = 4
432 = 96 + 4x
4x = 432 – 96 = 336
x = 336/4 = 84 km/h
