The mirror image of a clock shows a time of 4:25. Then the real time shown by the clock is:
The cost of price of an article is Rs.450. if a shopkeeper gains 20%profit even after a discount of 10%, find the market price of the article.
Profit = 450× 120/100
= 2540
Discount = 10% = 540
Market Price = 540 × 100/90
=600
In an examination, 60% students were successful. If the number of successful students was 240, find the number of unsuccessful students:
Total students 60% x =240
60/100(x) = 240
X = 400
∴ successful students = 240
∴ unsuccessful students = 400-240
Total students = 160
