Given :- Each time Princy smiles at Komal, she is rewarded Rs. 20 and each time she quarrels with Komal, she pays a penalty of Rs. 15. If this sequence of smiling and quarrelling continues, in how many sequences does Princy reaches the figure of Rs. 60 for the first ?

Answer :-

Let total times are 2x .

so, she smiles at x times and quarrels at x times .

then,

→ for smiles she gets = 20 * x = Rs.20x

and,

→ for quarrels she gives panelty = 15 * x = Rs.15x

A/q,

→ 20x - 15x = 60

→ 5x = 60

→ x = 12 .

hence, total sequence will be 2x = 2 * 12 = 24 . (Ans.)
