Answer 1

Answer:

cost of shirt S = 32

cost of belt B = 20

Step-by-step explanation:

given

A shirt cost 12 more than a belt

total cost of 2 shirts and 5 such belts was 164

let cost of a shirt is = S rupees

and cost of a belt is = B rupees

now

A shirt cost 12 more than a belt  means

S - B = 12      (1)

total cost of 2 shirts and 5 such belts was 164 means

2S + 5B = 164   (2)

now solve these equations

eq (1) multiply by 2 and substract from (2)

(2S + 5B = 164) - (2S - 2B = 24 )

7B = 140

B= 20

now put b = 20 in eq (1)

S - 20 = 12

S = 12 + 20

S = 32

cost of shirt S = 32

cost of belt B = 20
