Answer :
Given that for every 3 metres of the shirt material, he buys 2 metres so the ratio of shirt material brought to the trouser material bought = 3 : 2
Let the shirt material bought = 3x m
and trouser material bought = 2x m
Cost of shirt material = 50 × 3x = ₹ 150x
Cost of trouser material = 90 × 2x = ₹ 180x
Also, profit in case of shirt material=12%
∴ It's selling price=\(₹(150x×\frac{112}{100}\))=₹168x
Also, profit in case of trouser material=10%
∴ It's selling price=\(₹(180x×\frac{110}{100}\))=₹198x
∴ Total selling price=₹(168x+198x)=₹366x
But we have the total selling price as ₹36660
∴ 366x=36660
\(\Rightarrow\ x=\frac{36660}{366}=100.16\)
Thus, the trouser material purchased =2x=2×100.16m≈200 meters.
