The following Pie - Chart shows the interest gain on selling the five different types of Gold-Silver alloy Biscuits.

Price of Gold per 10 grams = Rs. 42,000

Price of Silver per kg = Rs. 42,000

Question 1: After one year, Ramesh sells 320 grams of B2 biscuits whereas Suresh sells 300 grams of B4 biscuits. What is the ratio of their interest gain?

A. 84504 : 132667

B. 88504 : 132867

C. 84506 : 132967

D. 84508 : 152867

E. 84504 : 132867

Right Answer is: E

SOLUTION

Price of Gold per 10 grams = Rs. 42000

42000/10 = Rs. 4200 per gram

Price of Silver per kg = Rs. 42000

42000/1000 = Rs. 42 per gram

In Biscuit B2,

Silver: Gold = 3 : 5

Silver = 320 × 3 / 8 = 120 grams

Cost of silver = 120 × 42 = Rs. 5040

Gold = 320 × 5 / 8 = 200

Cost of Gold = 200 × 4200 = Rs. 840000

Total Cost of B2 Biscuits = 5040 + 840000 = Rs. 845040

Now, Ramesh gets 10% interest on B2

∴ Interest = 845040 × 10/100 = Rs. 84504

In Biscuit B4,

Silver : Gold = 3 : 7

Silver = 300 × 3 / 10 = 90 grams

Cost of silver = 90 × 42 = Rs. 3780

Gold = 300 × 7 / 10 = 210 grams

Cost of Gold = 210 × 4200 = Rs. 882000

Total Cost of B4 Biscuits = 3780 + 882000 = Rs. 885780

Now, Suresh gets 15% interest on B4

∴ Interest = 885780 × 15/100 = Rs. 132867

∴ Ratio of interest gain = 84504 : 132867
