A=P(1+{r/2}/100)^(2n) where n is no. Of years
So
A=1600(1+{5/200})²+1600(1+{5/200})¹
A=1600×(41/40)²+1600×(41/40)
A=1600×{41/40}{1+(41/40)}
A=332Inter
So
Gain or Interest= 3321-3200
= 121 Rs.

Let the numbers be 3x, 4x and 5x.

Then, their L.C.M. = 60x.

So, 60x = 2400 or x = 40.

The numbers are (3 x 40), (4 x 40) and (5 x 40).

Hence, required H.C.F. = 40.

quantity of pure liq remained afer 2 itirations,quantity of pure liq remained=x*(1-y/x)^n
where y amount of liq replaced ,x quantity of pure liq or capacity of vessel
n number of repeations
so,32=x*(1-(10/x))^2
on solvingx=50 or 2 as it cant be 2 lit the ans will be x=50 lit

Moli buys 3 ribbons,7 clips and 1 soap for Rs.120 exactly. At the same place it would cost Rs.164 for 4 ribbons, 10 clips and one soap. How much would it cost for one ribbon, one clip and one soap?

3R+7C+S=120---------(a)
4R+10C+S=164---------(b)
on multiplying eqn (a) with 3 and eqn (b) with 2 ;
3a-2b=>R+C+S=3*120-2*164=32
