Question

Surendra, Rajendra and Manindra invested some amount in a business in the ratio of 5 : 7 : 6, respectively. In the next year, they increased their investments by 26 per cent, 20 per cent and 15 per cent respectively. The profit earned during the second year should be distributed in what ratio among Surendra, Rajendra and Manindra.

Answer 1

Answer:

Step-by-step explanation:

Let's say they invested 18,000 in total, so their individual investment in their old ratios are:

Surendra= 5,000

Rajendra= 7,000

Manindra=6,000

They increased their investments by 26, 20 & 15 % respectively, so the increase in their investments will be as follows:

Surendra: 5,000 * 26/100 = 1300

Surendra new investment= 5000+1300 = 6300

Rajendra: 7,000 * 20/100 = 1,400

Rajendra new investment= 7,000+1,400 = 8,400

Manindra: 6,000 * 15/100 = 900

Manindra's new investment= 6000+900 = 6,900.

So now we can find their new ratios, which will be

21:28:23

Answer 2

Answer:

The profit earned in second year should be distributed in 21 :28 : 23 ratio among Surendra, Rajendra and Manindra.

Step-by-step explanation:

The old ratio of investment by Surendra, Rajendra and Manindra is $5:7:6$

Consider that they invested total Rs.18000.

So, according to their old ratio their individual investment will be:

Surendra's investment $=Rs.5000$

Rajendra's investment $=Rs.7000$

Manindra's investment $=Rs.6000$

Now , their investment increase  26%, 20% and 15% respectively.

The increase in invetments is:

• Increment in Surendra's investment  $=5000 * \frac{26}{100} = 1300$

        Surendra's new investment $= 5000+1300 = 6300$

• Increment in  Rajendra's investment $=7000 *\frac{ 20}{100} = 1,400$

        Rajendra's new investment $= 7,000+1,400 = 8,400$

• Increment in Manindra's investment  $=6000 * \frac{15}{100} = 900$

        Manindra's new investment $= 6000+900 = 6,900.$

The new ratio is:- $6300:8400:6900$

                                  $21:28:23$
