Question
155 litres of a mixture contains 42% milk and rest
water. If βxβ litres of milk is added into the mixture then quantity of water in the final mixture becomes 31% of total quantity of mixture. Find the value of βxβ.Solution
Quantity of milk in the initial mixture = 155 Γ 0.42 = 65.1 litres Quantity of water in the initial mixture = 155 β 65.1 = 89.9 litres Quantity of water is unchanged in the final mixture. So, Quantity of final mixture = (89.9/31) Γ 100 = 290 litres Quantity of milk in final mixture = 290 β 89.9 = 200.1 litres Value of βxβ = 200.1 β 65.1 = 135
564.932 + 849.029 β 425.08 = 612.095 + ?
999.99 + 99.99 + 99= ?
