Alloy A contains metals x and y only in the ratio 3 : 4 and alloy B contains these metals in the ratio 5 : 1. Alloy C is prepared by mixing A and B in the ratio 3 : 2. The percentage of y (approx) in alloy C is:
Answer & explanation
Correct answer: option 2
x : y
A- 3 : 4 = 7 ) × 6 ×3
B- 5 : 1 = 6 ) × 7 ×2
x : y
A- 54 : 72
B- 70 : 14
C - 124 : 86
62 : 43 = 105
percentage of y in C = \(\frac{43}{105}\) × 100 = 41 (approx)
