Question

The price of 6 chocolates and 3 biscuit packets together is Rs126. The price of 10
chocolates and 3 biscuit packets is Rs186. What is the price of a chocolate? And the price of a biscuit packet?

Answer 1

Answer:

let the price of one chocolate = x

and price of one biscuit packet = y

so 6x +3y= 126. (1)

and 10x + 3y = 186. (2)

by multiplying 1 in both the equition

we get 6x = 126 - 3y

X = 126 -3y/6. (3)

Step-by-step explanation:

putting the value of X in 1st equition ,we get the value of Y = 12. (4)

put the value of Y in 3rd equition ,we get

X= 15

so the price of one chocolate = 15

and price of one biscuit =12
