Question

The cost of 2kg mangoes and 1kg apples is rs160.After a month cost of 4kg mangoes & 2kg apples is rs 300.Find the cost of 1kg mangoes & 1kg apples?

Answer 1

Ans = 82.5₹

Step-by-step explanation:

Let mangoes be x

Let apples be y

2x+y=160-----------1

4x+2y=300----------2

Divide 2 by 2

2x+y=150------------2

Subtracting 2 by 1

2x+y=160

-2x+y=150

=2y=10

Y=5₹

Put y=5 in 1

2x+5=160

2x=155

X=155/2

X=77.5₹

Cost of one mango and one Apple=77.5+5

=82.5₹

$\boxed{given}$

1KG APPLES COST IS rs. 72.20

$\boxed{find}$

$(a) cost \: of \: 6kg \: apples$

$(b)cost \: of \: 3.5kg \: apples$

$\boxed{solution}$

(a)

COST OF 1 KG APPLES = rs. 72.20

cost of 6 kg apples = 6×72.20

$= 6 \times \frac{7220}{100} = rs.433.2$

(b)

so, cost of 6 kg apple is

$\boxed{rs.433.2}$

and cost of 3.5kg apple is

$\boxed{= rs.259.92}$
