Question
In a jug, there is a mixture of apple and orange juice
in the ratio of p:3. When 10 liters of Apple are added, the ratio of Apple to orange juice becomes 5:3. Adding 20 liters of apple changes the ratio of apple to orange juice to 7:4.Determine the initial quantity of orange juice in the mixtureSolution
ATQ, we can say that Let the initial quantity of orange juice = 3m and initial quantity of Apple = xm ATQ, (xm + 10)/3m = 5/3 3xm + 30 = 15m (equation 1) Also (xm + 20)/3m = 7/4 4xm + 80 = 21m (equation 2) Solving equation 1 and 2, we get m =40 Initial quantity of orange juice = 3m =3 × 40 = 120 liters
(14.14 ×  29.98) + 20.15% of 549.99 = ? + 120.34
? = 44.78% of 839.91 – 48.12% of 774.89 + 55.77% of 1024.85
79.95 × 25.001 – 20.001 × 129.90 + 839.99 = ?
24.45% of 14.99% of 14999.78 + 159.80 = ?% of 1999.78
(2100.23 ÷ 34.98) + (864.32 ÷ 23.9) + 1854.11 =?
1959.09 + 33.94% of 6250.06 – ? = √10609.02 + √144.24
15.232 + 19.98% of 649.99 = ? × 4.99
149.78% of 319.87 – 199.83% of 45.45 = 130.03% of (? × 12.01)Â
