Answer

(i) Given, a man earns = ₹ 18,720 per month

Expenditure =56 of his income=56×18720=5×187206=5×3120=15,600.\text{Expenditure }= \dfrac{5}{6} \text{ of his income}\\[1em] = \dfrac{5}{6} \times 18720\\[1em] = \dfrac{5 \times 18720}{6}\\[1em] = 5 \times 3120\\[1em] = 15,600.

Hence, expenditure = ₹ 15,600.

(ii) Saving = Income - Expenditure

= 18,720 - 15,600

= ₹ 3,120.

Hence, saving = ₹ 3,120.
