Management Aptitude Test 2018 Paper

(a) Let the shares of A, B and C be a, b and c, respectively.
Then, a = $\frac{2}{9}$ (b + c) and a + b + c = 770
∵ a+ b + c = 770
⇒a + $\frac{9}{2}$ a = 770 $\left[\because \mathit{a}=\frac{2}{9}\left(\mathit{b}+\mathit{c}\right)\right]$
⇒ $\frac{11}{2}$ a = 770 ⇒ a = ₹ 140
Hence, share of A is ₹ 140
