The price of 8 books and 24 registers is Rs. 1760. If the price of one book is Rs. 124 more than the price of one register, what is the total price of 4 books and 2 registers ? (In Rs.)
Let price of 1 register = $$Rs. x$$
=> Price of book = $$Rs. (x + 124)$$
Acc. to ques, => $$8 (x + 124) + 24x = 1760$$
=> $$8x + 992 + 24x = 1760$$
=> $$32x = 1760 - 992 = 768$$
=> $$x = \frac{768}{32} = 24$$
Thus, price of book = $$24 + 124 = 148$$
$$\therefore$$ Total price of 4 books and 2 registers
= $$(4 \times 148) + (2 \times 24)$$
= $$592 + 48 = Rs. 640$$
