Answer 1

Answer:

10 & 15 & 28

Step-by-step explanation:

Let the price of pencil be Rs a.

So,

Price of pen = 5 more than a = a + 5

Price of book = 8 + 2 times of a = 2a + 8

Total amount = Rs 53

= > price of pencil + price of pen + price of book = Rs 53

= > a + (a + 5) + (2a + 8) = 53

= > a + a + 2a + 13 = 53

= > 4a = 53 - 13 = 40

= > a = 40/4 = 10

(A): price of pencil = a = Rs 10

(B): price of pen = a + 5 = 10+5 = Rs 15

(C): 2a + 8 = 2(10)+8 = 28
