Question

for uttrakhand flood victims two section a and b of class x contributed rs1500 ifthe contribution of xa was rs100 less than that xb find the graphical of amount contributed both section.

Answer 1

Contribution of section A :  Rs  X   let us say.
Hence,  the contribution of section B:   Rs  X + 100

Total contribution of the class:  X + X + 100 = 2 X + 100

so  2 X + 100 = Rs 1, 500
        2 X = Rs 1,400
           X = Rs  700

So section A contributed  Rs 700.
Section  B contributed  Rs 700 + 100 =  Rs 800.

Answer 2

Answer:

Contribution of section A :  Rs  X   let us say.

Hence,  the contribution of section B:   Rs  X + 100

Total contribution of the class:  X + X + 100 = 2 X + 100

so  2 X + 100 = Rs 1, 500

        2 X = Rs 1,400

           X = Rs  700

So section A contributed  Rs 700.

Section  B contributed  Rs 700 + 100 =  Rs 800.
