Answer 1

Answer:

Step-by-step explanation:

let consumption of cofee be x and tea be 5x

in 1st case total extra tea taken 5x* a/100

and cofee xb/100

total 5x* a/100 + xb/100

but it us given that total increased amt is 7%

means 7* ( 5x+x)/100

= 42x/100

so equating those we gate

5a + b = 42

same way we get 5b + a = 18

after that you have to solve 2 equation,

5a + b = 42 & 5b +a = 18. this 2 equation we have to solve

so, a=2, b=8.........
