Average age of A and B is 30 Years, that of B and C is 32 Years and the average age of C and A is 34 Years. The age of C is:
- 36
- 38
- 40
- 42
- a
-
Average of A & B is
( A+B) /2 = 30 ⇒ A+B=60 ⇒ A= 60 – B —- (i)
( B+C)/2 = 64 ⇒B+C = 64 ⇒ B= 64 – C—- ( ii )
Putting value of B in equation ( i )
⇒ A= 60 – 64 +C ⇒ A = -4 + C —– ( iii)
( C+A)/2 = 34 ⇒ C+A=68 ⇒ C = 68 – A —–(iv)
Puuting value of A from eaquation ( iii) to eq. (iv)
⇒ C= 68 +4 -C ⇒ C =36

A man buys an article for Rs.27.50 and sells it for Rs.28.60. Find his gain percent?
- 1%
- 4%
- 3%
- 5%
- b
-
Purchase = 27.50
Sale = 28.60
Profit = 28.60-27.50=1.1
Profit %age = 1.1/27.50*100
Profit %age = 4
