Answer 2

Answer:

(Q.1.) Let the selling price of the article be Rs.x.

Cost price of the article =Rs.1215

Money spent on transporting =Rs.35

Therefore,

Total cost price of the article =1215+35=Rs.1250

Now according to the question-

x=1250+16% of 1250

x=1250+

100

16

×1250

⇒x=1250+200=1450

Hence to gain 16%, he should sell the article for Rs.1450.

(Q.2.)Let the C.P. be Rs.x

S.P. =Rs.30

Profit %=25%

Now, according to question-

x+25% of x=30

x+ 25/100x=30

⇒x+ 1/4x=30

⇒5/4x=30

⇒x=30× 4/5

⇒x=24

Hence the dealer paid Rs.24 for the chair.
