enik 9438 anu kittiyath,10% alle interest, enganeya 9360 kittuka?

Compound interest nte engane aanu

9th qstion engana cheyyuka,3 speed varumbol

3*Lcm/sum
Lcm=60 aanu
So 3*60/(60/10+60/20+60/60)
=3*60/6+3+1
=3*60/10=18

7nth qsn
Lcm of 18,24,36=72
A+b=18 72/18=4
B+c=24 72/24=3
A+c=36 72/36=2
2*(a+b+c)=4+3+2
A+b+c=9/2=4.5
A=4.5-3=1.5(A illatha eqns yil kodukunu A kana)
B=4.5-2=2.5
C=4.5-4=0.5
So C=72/0.5=144

1 A+B 1/18
1 B+C 1/24
1 A+C 1/36

1 A+B+C (1/18 + 1/24 + 1/36)/2 = 3/48
1 C = ((A+B+C)-(A+B)) (3/48 -1/18) =1/144
144 C
