Question

If the cost of a dozen apples is ₹ 240, then

• A. ₹200
• B. ₹120
• C. ₹600
• D. ₹400

Answer 1

1 dozen is equal to 12 apples.

The cost of dozen apples = ₹ 240
then the cost of 1 apple = $\frac{240}{12}$ = ₹ 20

Hence,

The cost of 6 apples =
$20\times 6=₹120$
The cost of 10 apples =
$20\times 10=₹200$
The cost of 20 apples = $20\times 20=₹400$
The cost of 30 apples = $20\times 30=₹600$
