${ \huge \mathcal{\red{A} \green{N} \blue{S} \pink{W} \orange{E} \purple{R} \blue{ \: ! }}}$

Cost of 15 books =₹375

$\sf \large Cost \: of \: 1 \: book = \cancel\frac{375}{15}$

So Cost of 1 book = ₹25

No. of books bought for ₹25=1

$\sf No. \: of \: books \: bought \: for \: ₹675 = \cancel{\frac{1}{25} \times 675} \\ \\ \sf\!\!\!\!\!\!\!\!\!\!\!\!\!\!\! \!\!\!\!\!\!\!\!\!No. \: of \: books \: bought \: for \: ₹675 = 7$

So 7 books can be bought for ₹675.
