There was this question an hour back
The difference in CI earned on a certain sum for which interest is compunded anually , in the first and the second year is 160 .If the rate of interest becomes 4 times the original rate then the difference in the interests earned in the first and second year would be
I solved it like:
Amount = P (1+r/100)
CI = P (1 +r/100 ) - P = Pr/100 -> after first year
for second year
Amount = P (1+r/100)^2
CI = P(1+r/100)^2 - P
= P [ 1 +r^2 /10^4 + 2r/100 ] - P
= P [ r^2 /10^4 + 2r/100 ]
so:
P [r^2/10^4 + 2r/100 ] - P(r/100) =160
Pr^2 /10^4 + 2Pr/100 - Pr/100 =160
Pr^2/10^4 + Pr/100=160
P [ r^2 /10^4 + r/100 ]: whats wrong in my method ? please reply @happy3475 @anandmadhav @ankurkhanna14
have a doubt..ques like 1/x + 1/y = 1/n????
how to solve this?😠
One more help.any no expressed as a difference/sum of two square no??? how to find this?? @techgeek2050 @jaffa
