Two sections, A and B, of class X contributed a total of ₹ $\displaystyle 1500$ for the Uttarakhand flood victims. The contribution from X-A was ₹ $\displaystyle 100$ less than that of X-B. Graphically, find the amounts contributed by both sections.
Marking-scheme solution
Let $\displaystyle x$ and $\displaystyle y$ be the amounts contributed by the classes X-A and X-B respectively.According to question,
\[x+y=1500 \text { and } x=y-100 \text { or } y-x=100
\]∴ Amount contributed by class X-A = ₹ $\displaystyle 700$
and amount contributed by class $\displaystyle \mathrm{X}-\mathrm{B}=₹ 800$
