Question

What is the total cost of half watermelon (Rs 80 each), three-fourths of pumpkin (Rs 100 each) and two-fifths of a litre of milk (Rs 20 per litre)?

• A. Rs 100
• B. Rs 123
• C. Rs 132
• D. Rs 150

Answer 1

The correct option is B Rs 123

1 watermelon costs Rs. 80

$\therefore$ half a watermelon costs = 80/2 = Rs.40

1 pumpkin costs Rs.100

$\therefore$ 3/4 pumpkin costs

=$\frac{3\times \text{/}1\text{/}0\text{/}0}{\text{/}4}$ = 25

=$3\times 25=Rs.75$

1 litre of milk costs Rs.20

$\therefore$ 2/5th of a litre costs

=$\frac{2\times \text{/}2\text{/}0}{\text{/}5}$ = 4

=$2\times 4=Rs.8$

Total cost of 1/2 a watermelon + 3/4th of a pumpkin =40 + 75 + 8 = Rs. 123 and 2/5th of a litre of milk

Answer: B Rs. 123
