Question
100 litres of a mixture contains 40% milk and rest
water. If βxβ litres of milk is added into the mixture then quantity of water in the final mixture becomes 25% of total quantity of mixture. Find the value of βxβ.Solution
Quantity of milk in the initial mixture = 100 Γ 0.40 = 40 litres Quantity of water in the initial mixture = 100 β 40 = 60 litres Quantity of water is unchanged in the final mixture. So, Quantity of final mixture = (60/25) Γ 100 = 240 litres Quantity of milk in final mixture = 240 β 60 = 180 litres Value of βxβ = 180 β 40 = 140
564.932 + 849.029 β 425.08 = 612.095 + ?
999.99 + 99.99 + 99= ?
