A) Rs. 5500 B) Rs. 6000
C) Rs. 6200 D) Rs. 6350
 
Answer & Explanation Answer: B) Rs. 6000

Explanation:

The wages of labourers in a factory increases in the ratio 22:25 and there was a reduction in the number of labourers in the ratio 15:11. Find the original wage bill if the present bill is Rs 5000 ?
Ratio of increase of wages = 22:25
Ratio of decrease of labourers = 15:11
Compound ratio of wages of labourers = 22 x 15 : 25 x 11 = 330:275
Final bill = Rs. 5000
For 275 ratio wages = Rs. 5000
For 1 ratio wages = 5000/275
For 330 ratio wages = 5000/275 x 330 = Rs. 6000

Q:

What annual payment will discharge a debt of Rs.7620 due in 3years at1623 % per annum interest?

A) 5430 B) 4430
C) 3430 D) 2430
 
Answer & Explanation Answer: C) 3430

Explanation:

Let each installment be Rs.x. Then, 

(P.W. of Rs.x due 1 year hence) + (P.W of Rs.x due 2 years hence) + (P.W of Rs. X due 3 years hence) = 7620.

 

x1+503x100+x1 +503x1002+x1 +503x1003 = 7620

 

 6x7+36x49+216x343=7620

 

 294x + 252x + 216x = 7620 x 343

 

 => x = 3430

 

 Amount of each installment = Rs.3430
