Marks: +1, -0

A shopkeeper buys 144 items at 90 paise each. On the way 20 items are broken. He sells the remainder at ₹ 1.20 each. His gain per cent correct to one place of decimal is

13.8%
14.6%
14.8%
15.8%

Validate

Solution:

(3) 20 items are broken out of 144 items.
∴ C.P. of 124 items

= {Rs} ( {144 × 90}/{100} )= {Rs} .129 .60

Total S.P. = Rs. (1.20 × 124) = Rs. 148.8
∴ Gain = Rs. (148.80 – 129.60) = Rs. 19.20
∴ Gain percent

= {19.20}/{129.60}× 100=14.8 \%
