Question

Alex bought 8 oranges at ₹ 64 from a shop. Ben bought 10 oranges from another store at ₹ 90. If Ben had bought his oranges from the same store as Alex, how much less would he have paid in all?

• A. ₹ 11
• B. ₹ 10
• C. ₹ 12
• D. ₹ 13

Answer 1

The correct option is B ₹ 10

Alex bought 8 oranges at ₹ 64
$\Rightarrow$ Cost of each orange $=\frac{64}{8}=₹8$

Ben bought 10 oranges at ₹ 90 from another store.
$\Rightarrow$ Cost of each orange $=\frac{90}{10}=₹9$

If Ben bought his oranges at the same store as Alex, he would have paid ₹ 8 for each orange, then he would have paid
$10\times 8=₹80$

$\therefore$ if Ben would have gone to the same store as Alex, he would have paid 90 - 80 = ₹ 10 lesser
