Answer 1

Answer:

Step-by-step explanation:

Given  

A man invested Rs 6750 partly in shares Of 6% at Rs 140 and partly in shares of 5%at 125 if his total income is Rs 280 how much has he invested in each.

ANSWER

Let the investment of the man in shares paying 6% at Rs 140 is Rs x and that of 5% at Rs 125 be Rs (6750 – x)

Income on one share of Rs 140 is Rs 6

So income of Rs x = 6/140 x x = Rs 3 x / 70

Income on one share of Rs 125 = Rs 5

So income on Rs 6750 – x = 6750 – x / 125 x 5 = 1/25(6750 – x)

Now total income is Rs 280

3 x /70 + 6750 – x / 25 = 280

15 x + 94,500 – 14 x / 350 = 280

15 x + 94,500 – 14 x = 280 x 350

 x = 3500

Now 6750 – x = 6,750 – 3500 = Rs 3,250

Investment in buying shares at 6% is Rs 3500 and

Investment in buying shares at 5% is Rs 3250.
