121. If the total weight of 6 Apple and 9 Orange is 180 kg and the total weight of 7 Apple and 5 Orange is 144 kg, then find the weight of 3 Orange?

यदि 6 सेब और 9 संतरे का कुल वजन 180 किग्रा है और 7 सेब और 5 संतरे का कुल वजन 144 किग्रा है, तो 3 संतरे का वजन ज्ञात करें?

A. 36 kg
B. 42 kg
C. 45 kg
D. 33 kg
E. None of these

Option “A” is correct.

6A + 9O = 180

2A + 3O = 60 —-(1)

7A + 5O = 144 —-(2)

21O – 10O = 132

O = 12

Weight of three oranges = 12 * 3 = 36 kg

122. If the ratio of a: b = 2: 3, b: c = 3: 4 , c: d = 2:3 , e: d = 2:1 . Then find the ratio of a: b: c: d: e?

यदि a: b = 2: 3, b: c = 3: 4 , c: d = 2:3 , e: d = 2:1 . तो a: b: c: d: e का अनुपात ज्ञात कीजिए?

A. 2: 3: 4: 6: 3

a/b = 2/3

b/c = 3/4

c/d = 2/3 * 2/2 = 4/6

e/d = 2/1

d/e = 1/2 * 3/3 * 2/2 = 6/12

a: b: c: d: e = 2: 3: 4: 6: 12

123. The number of male employees in a company is 60% more than the number of female employees in the company. If the number of female employees is increased by 40% and the number of male employees is decreased by 25%, then find the ratio of the number of male to female employees in the company?
