Question : 2
Price of an article is marked up 50% above the cost price. If the discount offered in the article is Rs. 50 and the profit earned is also Rs. 50, what is the marked price of the article?
a) Rs. 200
b) Rs. 240
c) Rs. 300
d) Rs. 450
e) Rs. 600
Answer »Answer: (c)
Let the cost price of the article = Rs. 100x, then
Marked price of the article = 100x + 50% of 100x = Rs. 150x
The selling price of the article = Rs. (150x – 50)
According to question
Profit = SP – CP
50 = (150x – 50) – 100x
⇒ 50 = 50x – 50
⇒ 50x = 100
⇒ x = 2
Hence, the marked price of the article = Rs. 150x
= 150 × 2
= Rs. 300.
Question : 3
A boat travels upstream at the speed of 10 km/hr for t hours and downstream at the speed of 14 km/hr for 6 hours. If the distance travelled in downstream direction is 44 km more than that in upstream direction, then what is the value of t?
a) 7
b) 2
c) 3
d) 4
e) 6
Answer »Answer: (d)
Distance = Speed × Time
The distance travelled in downstream direction
= 14 × 6 = 84 km
The distance travelled in upstream direction
= 10 × t = 10t km
According to question
84 – 10t = 44
⇒ 10t = 84 – 44 = 40
⇒ t = $40/10$ = 4
