According to the question,
5% of y = 10⇒ 5y = 10 100
Correct Option: C
Let C.P. of watch = Rs. y
Difference between selling prices = Rs. (350 – 340) = Rs. 10
According to the question,
5% of y = 10⇒ 5y = 10 100
⇒ 5y = 1000⇒ y = 1000 = Rs. 200 5
Hence , C.P. of watch is Rs. 200 .

Case I :
Suppose C.P. of article = Rs. y
At 10% loss ,First S.P. = Rs. 9y 10
Case II :
At 20% less ,C.P. = 80y = Rs. 4y 100 5
According to the question,4y × 140 - 9x = 55 5 100 10 ⇒ 56x - 9y = 55 50 10
Correct Option: C

Given that , C.P. of two articles = Rs. 520
Suppose C.P. of article sold at loss = Rs. y.
∴ C.P. of article sold at profit = Rs. (520 – y)
According to the question,y × 10 = (520 – y) × 16 100 100
⇒ 5y = 520 × 8 – 8y
⇒ 13y = 520 × 8⇒ y = 520 × 8 = Rs. 320 13
Correct Option: A

Let the C.P. of article be Rs. y.
According to the question,y × 105 - y × 80 = 200 100 100
⇒ 105y – 80y = 20000
⇒ 25y = 20000⇒ y = 20000 = Rs. 800 25
Using the given formula :
Here, a = 20%, R = 200, b = 5%C.P. = R × 100 b + a
Correct Option: A
