Completely i cant understand. Why 11% of stock is being multiplied with 117 why not with 143?

Completely I can't understand the problem please explain briefly.

Alternate way in 1st case u get rs 11 on investing rs143.
so for getting 1 rs u have to invest 13 rs
similarly in 2nd case u have to invest 12 rs for getting 1.so second one is profitable.

Alternate
1 case: if we invest rs 143 we get a profit of 11 rs therefore 100 rs how much
i.e 143 rs invest 11 rs profit
100 rs ?

(100*11)/143=7.69 rs profit

2 case: if we invest rs 117 we get 9.75 rs profit therefore for 100 rs how much?
i.e 117 rs invest 9.75 rs profit
100 rs ?

(100*9.75)/117=8.333 rs profit


From above we can clearly make out that 2 case is best...

I hope you understood the logic.

@Nagendramurthy. Your explanation is the best.

Its 11% at the stock...which means we get rs 11 if we invest rs 100 in it..as percentage is always considered in 100. plz clarify me

Income->investment

11----->143.
39/4--->117.

Solution: here we can compare only after equating 2 investments.

So,
11*117--->143*117==>here income is 1287.
39/4*143->117*143==>here income is 1394.25

@Mr. Vikas don't care about the problem in reality way try to understand the given problem.

Its clear that 11% stock is once with of 117 and once with 143 so its simply multiply by those two and compare that two answers ok na. Did you get it.

11% Means in the real world 11/100 not 11/143.
11% on 143 is 15.73.
9.75% or 9 3/4 % on 117 means 11.40.

If you invest 143 you get 15.73 143 ===> 15.73.
If you invest 117 you get 11.40 117 ===> 11.40.

Please clarify how could you determinate 11% = 11 for 143?

Without knowing face value, how can the comparisons be made?
