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%?
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?
please help me in english sub iam so poor
what should i do to resolve reasoning problems...
what is the highest number of 12 in 100!?
In this question 12=2^2*3
Should I find highest number of 4 in 100! or 2 in 100! and then divide by 2 further?
I'm only confused about how to calculate the highest no of 4 in 100!
the maximum exponential power of a number in x!=[x/a]+[x/a^2]+.....
here [z] denote highest integer less than z
This is applicable only if a is prime
if u wnat to find for 12. find for 2 and 3. now 12=4*3. so halve the max exponential power of 2. let it be y. if the exponential power of 3 be z. if y>z then max exponential power of 12 will be z. or else it is y
