Question

Ram bought 6 books at ₹ 60 from a bookstore. Shyam bought 5 books from another store at ₹ 55. If Shyam had bought his books from the same store as Ram, how much lesser would he have to pay?

• A. ₹ 10
• B. ₹ 5
• C. ₹ 15
• D. ₹ 20

Answer 1

The correct option is B ₹ 5

Ram bought 6 books at ₹ 60
$\Rightarrow$ Cost of each book $=\frac{60}{6}=₹10$

Shyam bought 5 books at ₹ 55 from another store.
$\Rightarrow$ Cost of each book $=\frac{55}{5}=₹11$

If Shyam bought his books at the same store as Ram, he would have paid ₹ 10 for each book
$\Rightarrow$He would have paid
$5\times 10=₹50$

$\therefore$ If Shyam would have gone to Ram's store, he would have paid 55 - 50 = ₹ 5 lesser.
