The marked price of an article is increased by 25% and the selling price is increased by 16.66%, then the amount of profit doubles. If the original marked price be Rs. 400 which is greater than the corresponding cost price by 33.33%, what is the increased selling price?
Options- A. Rs. 380
- B. Rs. 420
- C. Rs. 460
- D. Rs. 440
- Correct Answer
- Rs. 420
ExplanationAs given in the question, Marked price is 25% more than the Cost price.
=> C.P of the article =
Now,
Let the original S.P of the article be Rs. P
Now the new S.P = P +
=> S.P =
According to the question,
=> 5P = 1800
=> P = Rs. 360
Hence, the increased S.P = 360 x 7/6 = Rs. 420.

Correct Answer: 36 sq.m
Correct Answer: 5%
Explanation:
Given compound interest for 3 years = Rs. 1513.2
and simple interest for 5 years = Rs. 2400
Now, we know that C.I =
=> 1513.2 = ...........(A)
And S.I = PTR/100
=> 2400 = P5R/100 ..................(B)
By solving (A) & (B), we get
R = 5%.
Correct Answer: 4
Explanation:
Correct Answer: 6
Explanation:
Let us assume Amount be 100 Rs and we calculate in CI
First year 60% of 100 = 60 amount (100+60) is 160
Second year 60% of 160 = 96 amount (160+96) is 256
Third year 60% of 256 =153.6 amount (256+153.6) is 409.6
Here the Amount of 100 Rs is quadrapled in 3 years.
One year contains 2 half years
Three year has 6 half years.
Therefore, It takes 6 half years.
