Question

The cost of 10 apples and 3 mangoes is Rs.51. The cost of 7 apples and 5 mangoes is Rs.56. Find the cost of 3 apples and 4 mangoes.​

Answer 1

Step-by-step explanation:

take apples as x and mangoes as y

then

10x+3y=51

7x+5y=56

by eliminating

We get x= 7

and

y= 3

so

3x+4y will be 3*7+4*3 which is 21+12=33
