ratio 1:4. The resulting mixture will have
water and milk in the ratio. (MQB)
a) 31:74 b) 31:75 C) 30:77 d) None​

Answer 1

Answer:

uantity of water in the resultant mixture

1*1/3 + 4*2/7 = 1/3 + 8/7 = 31/21

Quantity of milk in the resultant mixture

1*2/3 + 4*5/7 = 2/3 + 20/7 = 74/21

Required ratio

31/21 : 74/21

= 31 : 74
