trick

(2*3*12)/(3*3)+(5*2)

Ps bro.. Are u there?

simple intrst …simple formula…..

for ci

for 2 years

ci= 2(p*r%)+ (x*r%)

where x= p*r%

for 3 years

ci= 3(p*r%)+ 3(x*r%) + (y*r%)

where x= p*r% and y=x*r%

yaa…i have posted two ques

63×42/(63+42)

Now divide it by 82/5=42/5

U will get the ans…… Enjoyyyyyy

Know Hindi?

bro i said i have taken b=2a ……..i got a= 3 and b=6

i know i have taken wrong
