• Option : D
• Explanation : (D) If the ratio is 1 : 4, Then the number of defective bulbs = x and number of good bulbs = 4x

So, 1 : 4 is not possible.

• Option : D
• Explanation : (D) Let the production of Y =100
Then, production of X =120
Production of Z =150
Required ratio of X, Y and X
=X : Y : Z
=120 : 100 : 150
=12 : 10 : 15

• Option : A
• Explanation : Lets consider x% of 180.5 = 36.1
x% = 36.1/180.5
x = 36.1/180.5 × 100 = 20%

• Option : C
• Explanation : Let original price = 100
Original quantity = 100
Total expenditure = 100 × 100
New price = 100 + 25 = 125
New quantity = Q
As expenditure is to be kept same, 100 × 100 = 125 × Q
Q = (100 × 100)/125 = 80. % reduction in quantity = 100 - 80 = 20
