Sonu and Titu entered into a partnership for a year in which Sonu invested Rs 120000 and Titu invested Rs 70000. After 4 months, Sonu invested Rs 80000 more whereas after 5 months, Titu invested Rs 30000 more. When two months were left Sweety also joined investing Rs 400000 as her contribution. If the profit for the year was 12.5% of 1572000, find the share of Sonu, Titu and Sweety.

B
Sonu : Titu : Sweety

(120000 × 4 + 200000 × 8) : (70000 × 5 + 100000 × 7) : (400000 × 2)

208 : 105 : 80

Now,

12.5% of 1572000 = 196500

Therefore, Profit of:

Sonu =  208  × 196500 = Rs. 104000
393

Titu =  105  × 196500 = Rs. 52500
393

Sweety =  80  × 196500 = Rs. 40000
393

Hence, option B is correct.

A man can swim to a place 120 km distant and come back in 35 hours. He finds that he he can swim 6 km against the stream in the same time as 8 km with the stream. Find the ratio of speed of man in still water to that of stream?
» Explain it
C
Let he moves 8 km downstream in x hours.

Downstream speed =  8
x
Upstream speed =  6
x

Then,
 
⇒  120  +  120  = 35
8/x 6/x

⇒ 120 ×  7x  = 35
24

⇒ 35x = 35

⇒ x = 1

Then downstream speed = 8 km/h

Upstream speed = 6 km/h
 
U =  8 + 6  = 7 km/h
2

V =  8 – 6  = 1 km/h
2

Required ratio = 7 : 1

Hence, option C is correct.

Shilpa took a loan of Rs. 15,00,000 to purchase a car. The company charges compound interest at 20% per annum. She promised to make the payment after three years. But for the last year of loan tenure, the company increased the rate of interest by 25% from the previous one. Then the extra amount which she had to pay is what per cent of the amount of loan taken by her?
» Explain it
D
The rate of interest for first two years = 20% per annum

The rate of interest for last one year = 125% of 20 = 25%

According to question-

⇒ 1500000 × (1.2)2 × (1.25) – 1500000 (1.2)3

⇒ 1500000 × (1.8 – 1.728)

⇒ 1500000 × 0.072

⇒ 108000

Reqd. % =  108000  × 100 = 7.2%
1500000

Hence, option D is correct.

Ajay walked 12 km to reach the station from his house. Then he boarded in a train and reached his destination. The average speed of the entire journey was 62 kmph and he took a total time of 6 hours. If the average speed of train was 120 kmph, then what is the ratio of walking speed of Ajay to the speed of train?
» Explain it
A
Let the time travelled in train be 'x' hours

Total distance = 62 × 6 = 12 + 120 × x

⇒ 372 = 12 + 120x

⇒ x = 3

So, Ajay walked for (6-3) = 3 hours

Walking speed of Ajay

Distance covered by walking  =  12  = 4 kmph
Time taken by walking 3

Required ratio = 4 : 120 = 1 : 30

Hence, option A is correct.
