Step-by-step explanation:
ramans ratio is 2:3
so in 150ml there are 2 parts of juice and 3 parts of water
2x + 3x = 150
x = 30
so, juice in 150 ml of raman's mixture = 2x = 2* 30 = 60ml
meera ratio is 1:4
similarly,
1y + 4y = 100
y = 20
so, juice in 100 ml of meera's mixture is y = 20ml
so, quanitity of juice in final mixture is 60 + 20 = 80
