उत्तर : 4. "120 litres"
व्याख्या :

Answer: D) 120 litres Explanation: wine(left)wine(added) = 343169   It means  wine(left)wine(initial amount) = 343512    (since 343 + 169 = 512)    Thus,  343x = 512x1 - 15k3    343512 = 783 = 1 - 15k3    1-15k=78=1-18    Thus the initial amount of wine was 120 liters.

उत्तर : 4. "11 & 9"
व्याख्या :

Answer: D) 11 & 9 Explanation: Let the number of apples in each tree of the 5 farmers be a, b, c, d,e respectively. Therefore total no of apples are 7a, 9b, 11c, 13d and 14e respectively. Given, 7a+1 = 9b+3 = 11c-1 = 13d+3 = 14e-6 = x 9b+3 = 13d+3===> 9b = 13dso take b = 13 and d = 9 9b+3 = 9*13+3 = 120 ie, x=120 substituting7a+1 = 1207a = 119a = 17 11c-1 = 12011c = 121c=11 14e-6 = 12014e = 126e = 9 Yields per tree in the orchards of d 3rd & 4th farmers= 11,9
