Question

15 kg of a product is made by mixing three ingredients A B C in the ratio 3:2:5 by weight. The prices of the ingredients A B C per kg are in the ratio 5:7:2
The difference between the prices of the ingredients; A and C is Rs. 18 per kg, find the cost of the product

Answer 1

Answer:

RS 232

Step-by-step explanation:

WEIGHT:

A= 3/10*15=4.5 KG

B= 2/10*15=3 KG

C= 5/10*15=7.5 KG

C - A =3 KG

(3*18)=48RS.

COST:

A=5/14*15= 5X RS(APPROX.)

B=7/14*15=7.5X RS

C=2/14*15= 2X RS (APPROX.)

5X-2X=48

=> X=16

(5*16)+(7.5*16)+(2*16)= 232 RS
