Question

A person was engaged o n £720 a year and a golden ring. He served for 8 months and received £600. What was the price of the ring?​

Answer 1

Answer:

£360

Step-by-step explanation:

This is a question about equal proportions or rates. A person was promised to be paid £720 and a ring, with unknown cost R, for working 12 months, or a rate of (£720 + R)/12. He worked 8 months, and got paid (£600 + R).

So, assuming he got paid at the same rate,

(720+R)/12 = (600+R)/8

2(720+R) = 3(600+R)

1440 + 2R = 1800 + 3R

R = £360
