Question

A man spends Rs 660 on tables and chairs. the price of each table is Rs. 150 and the price of each
chair is Rs. 20. If he buys maximum number of tables, what is the ratio of chairs to tables purchased?
(a) 2: 5
(b) 3:5
(c) 2:3
(d) 3:4

Answer 1

Let number of chairs bought be x

and number of tables bought be y.

It is given that the price of each table is Rs. 150 and the price of each

chair is Rs. 20.

As Given , Man buys maximum number of  tables

So ,equation is given by → 150 y + 20 x = 660

1st method:

Multiple of 150 nearest to 660 is Rs 150 × 4 = Rs 600, so man spends Rs 600 on table.

Remaining Amount = Rs 660 - Rs 600= Rs 60

Price per chair = Rs 20

Number of chairs man can buy from Rs 60 is = 60 ÷ 20 = 3 chairs

→Ratio of chairs to tables = 3:4

Option (d)3:4 ,  is correct.
