There were 200 fishes in an aquarium, 99% of which were red. How many red fishes must be removed to make the percentage of red fishes to 98%?
Hi Aditya,
The total number of fishes in the aquarium are 200. We have been given that 99 percent of these are red. So the number of red fishes would be .99*200 = 198.
Now let's say that after removing 'k' red fishes, we have 98 percent red fishes in the aquarium.
So we have
198 - k = .98( 200 - k)
=> 198 - k = 196 - .98k
=> .02k = 2
=> k = 100
Thus, we need to remove 100 red fishes to make their percentage 98%.

A sum was lent at 20% p.a compound interest, the interest being compounded annually. Rs. 1200 was paid back after 1 year. after another year rs. 1440 was repaid to clear the loan. find the sum lent?
consider 2nd year. he has paid 1440 and clear the debt.
so the let amount remaining after 1st year (giving 1200) be 'P'
p(1+(20/100))^1=1440
p=1200
so the total amount after 1st year =1200+1200=2400
p(1+(20/100))^1=2400
p=2000
1200/1.2 + 1440/1.2*1.2 = 2000rs.

how to score increse in english
Hi Karthik
You first need to figure out your strengths and weaknesses. You need to understand that which topic in English is pulling down your scores. If it is RC then you have read regularly and take more mock tests to improve your accuracy. If the problem is with grammar questions then you have to go through the rules from some good book.
Hence before you start looking for the solution, you need to undertstand the problem areas. Hope that helps.
Thanks
