Question

Ayesha bought 1.80 m of cloth for her salwaar and 2.25 m for her kurta. If the cloth costs 120 rupees per metre, how much must she pay the shopkeeper?

Answer 1

Length of cloth bought for salwaar = 1.80 m

Length of cloth bought for kurta = 2.25 m

∴ Total length of cloth bought

= Length of cloth bought for salwaar + Length of cloth bought for kurta

= 1.80 m + 2.25 m

= 4.05 m


$\begin{array}{ccccc}& \overline{)1}& & & \\ & 1& .& 8& 0\\ +& 2& .& 2& 5\\ & 4& .& 0& 5\\ & & & & \end{array}$
Rate of cloth = Rs 120/m

∴ Amount paid to the shopkeeper

= Total length of cloth bought × Rate of cloth

= 4.05 m × ₹ 120/m

= ₹ 486

$\begin{array}{cccccc}& & & 4& 0& 5\\ & & \times & 1& 2& 0\\ & & & 0& 0& 0\\ & & 8& 1& 0& \times \\ & 4& 0& 5& \times & \times \\ & 4& 8& 6& 0& 0\\ & & & & & \end{array}$
Thus, Ayesha paid ₹ 486 to the shopkeeper.
