Answer 1

Given:

The first seller quoted the price of 5 pens and 7 pencil as ₹ 55 1/3 and ₹ 14 2/3 respectively .

The second seller quoted the price of 7 pens and 5 pencils as ₹ 78 2/5 and 10 3/4 respectively

To find:

From where should we buy?

Solution:

Price quotes given by the first seller:

Price of 5 pens = ₹ $55\frac{1}{3}$ = ₹  $\frac{165}{3}$ = ₹ 55

∴ Price of 1 pen = $\frac{55}{5}$ = ₹ 11

Price of 7 pencils = ₹ $14\frac{2}{3}$ = ₹  $\frac{44}{3}$ = ₹ 14.67

∴ Price of 1 pencil = $\frac{14.67}{7}$ = ₹ 2.09

Price quotes given by the second seller:

Price of 7 pens = ₹ $78\frac{2}{5}$ = ₹  $\frac{392}{5}$ = ₹ 78.4

∴ Price of 1 pen = $\frac{78.4}{7}$ = ₹ 11.2

Price of 5 pencils = ₹ $10\frac{3}{4}$ = ₹  $\frac{43}{4}$ = ₹ 10.75

∴ Price of 1 pencil = $\frac{10.75}{5}$ = ₹ 2.15

From the above calculations we can conclude that since the price quoted by first seller for 1 pen and 1 pencil is less than that of the price quoted by the second seller

Thus, we should buy from the first seller .
