​

Answer 1

Answer:

) Rs. 62500; Rs. 37500 B) Rs. 5733; Rs. 7865 C) Rs. 7297; Rs. 9865 D) Rs. 5242; Rs. 8906

Ans: A) Rs. 62500; Rs. 37500

Answer 2

Step-by-step explanation:

Then , 10% of x = 12% of y = 15% of z

x:y:z = 1/10 : 1/12 : 1/15

= 6:5:4

Let the ratio as 600:500:400

Then c = 1500

Interests are 60,60,60

Then , 180/1500 *100 = 12%
