1546 . During a sale, a salesperson was putting a new price tag on each item. On one shirt, he accidentally raised the price by 15% instead of lowering the price by 15%. As a result the price on the tag was Tk. 60 higher than the price that would have been the discounted price. What was the original price of the shirt?

A. Tk. 220
B. Tk. 250
C. Tk. 150
D. Tk. 200
E. None of these

View Answer	Favorite Question	Report

Answer: Option D

Explanation:

Price after 15% discount = 100 - 15 = 85 TK.

Price after 15% raise = 100 + 15 = 115

Price difference = 115 - 85 = 30 TK.

If price difference is 30 TK. then original price is 100 TK.

If price difference is 60 TK. then original price is 100 x 60 / 30 = 200 TK

and Adil age was = 8P/8 = P years
after 8 years later,
present age of Zaber = 8P+8 and Adil = P+8

8P+18 = 2(P+18)
4P+9 = P+18
3P = 9
P = 3

Answer: Option D

Explanation:

Let the present age of father be x and that of his Son Be y

Then 18 years ago

Father's age =x−18

Son's age =y−18

But given that

x−18=3(y−18)

⇒x−18=3y−54

⇒x−3y+36=0 (1)

Also given that x=2y (2)

From (1) & (2)

x−3y=36=0

⇒2y−3y+36=0

⇒y=36

Putting y=36 in (2)

x=2y

=2×36

=72

Sum of their present ages

=x+y

72+36

=108
