• x apples $\longrightarrow$ 108

• $\frak {Do\:Cross\:Multiplication}$

• $\tt 108 \times 15 = 90x$

• $\tt \dfrac{108 \times 15}{90} = x$

• $\tt \dfrac{108 \times \cancel15}{\cancel90} = x$

• $\tt \dfrac{108}{6} = x$

• $\tt \cancel \dfrac{108}{6} = x$

• $\tt x = 18$

• $\therefore$ $\tt \: 18 \: apples \: can \: be \: purchased \: for \: ₹108$
