Question

the cost of 5 pencils and 6 erasers is rupees 1.80 where as that of 3 pencils and erasers is 92 Paisa find the cost of each of a pencil and eraser​

Answer 1

Step-by-step explanation:

5p+6e=1.8-------(1)

3p+1e=0.92------(2)

Multiplely equation (2) with 6

18p+6e=5.52

5p+6e=1.8

----------------------

13p=3.72

p=0.286

substitute value p in equation (2)

3×0.286+e=0.92

0.858+e=0.92

e=0.92-0.858

e=0.0615

(In the question the no erases is not mentioned so I have taken it as 1)
