Question

Ronat bought $2\frac{1}{2}$ kg of mangoes at the rate of ₹ 60 per kg, $1\frac{1}{4}$ kg of lychees at the rate of ₹ 80 per kg, and $2\frac{3}{4}$ kg of watermelon at the rate of ₹ 40 per kg. How much did Ronat spend in total?

• A. ₹ 300
• B. ₹ 320
• C. ₹ 350
• D. ₹ 360

Answer 1

The correct option is D ₹ 360

Let's calculate the amount he paid for each item.
Ronat got $2\frac{1}{2}or\frac{2\times 2+1}{2}or\frac{5}{2}$ kg of mangoes at the rate of ₹ 60 per kg.
So, he spent $₹60\times \frac{5}{2}=₹150$ for the mangoes

Next, he got $1\frac{1}{4}or\frac{5}{4}$ kg of lychees at the rate of ₹ 80 per kg.
So, he spent $₹80\times \frac{5}{4}=₹100$ for the lychees.

And last, he got $2\frac{3}{4}or\frac{11}{4}$ kg of watermelon at the rate of ₹ 40 per kg.
So, he spent $₹40\times \frac{11}{4}=₹110$ for the watermelon.
So, the total amount Ronat spent is
₹ 150 + ₹ 100 + ₹ 110 = ₹ 360
