Question

Raju bought 6 books at ₹ 60 from a bookstore. Shyam bought 5 books from another store at ₹ 75. If Shyam had bought his books from the same store as Raju, how much less would he have paid in all?

• A. ₹50
• B. ₹25
• C. ₹70
• D. ₹45

Answer 1

The correct option is B ₹25

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

Shyam bought 5 books at ₹ 75 from another store.
$\Rightarrow$ Cost of each book $=\frac{75}{5}=₹15$

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

$\therefore$ if Shyam would have gone to the same store as Raju, he would have paid 75 - 50 = ₹ 25 lesser
