Question

The cost of 6 school bags and 4 umbrellas is Rs. 3180/- and the cost of 6 school bags and 2 umbrellas is Rs. 2940. Find cost of each .

Answer 1

Answer:

school bag = rs.450

umbrella = rs.120

Step-by-step explanation:

cost of school bag= x

cost of umbrella= y

6x+4y=3180. ---> (1)

6x+2y=2940. -----> (2)

subracting (2) from (1)

6x+4y=3180

- 6x+2y=2940

——————

2y=240

——————

=> Y=120.

substituting y in (2)

6x+2[120]=2940

=> 6x=2940-240

6x=2700

X= 450.

Hope this helps ☺️
