Question

A PERSON EARNS RS 100 IN A DAY. IF HE SPENDS RS 31/2 ON FOOD AND RS 61/3 ON RENT HOW MUCH DID HE SAVE ON THAT DAY

Answer 1

Step-by-step explanation:

Total earning of the person= ₹100

Amount he spends on food= ₹31/2

Amount he spends on rent = ₹61/3

Amount he spends= 31/2+61/3

$\frac{31}{2} + \frac{61}{3} \\ \\ \frac{31 \times 3 + 61 \times 2}{6} \\ \\ \frac{93 + 122}{6} \\ \\ \frac{215}{6}$

Money he saved= Money he had - Money he spent

$100 - \frac{215}{6} \\ \\ \frac{100 \times 6 - 215}{6} \\ \\ \frac{600 - 215}{6} \\ \\ \frac{385}{6}$

Money he saved= ₹385/6
