   Total no of cars in state 4 = 26% of 700 = 182
   Number of petrol engine cars in state 4 = 182 * 1/2 = 91
   Required difference = 91 – 70 = 21
   
   
7. Number of petrol engine cars in state 3 is what percent more than the number of diesel engine cars in state 1?
   A. 200%
   B. 300%

   Number of diesel engine cars in state 3 = 224* 5/8 = 140
   Number of diesel engine AC cars in state 3 = 25% of 140 = 35
   Number of diesel engine non-AC cars = 140-35 = 105

    C. 85.25
    D. 89.25
    
    Answer & Explanation

    Answer – D. 89.25
    Explanation :
    Total no of cars in state 1 = 14% of 700 = 98
    Total no of cars in state 2 = 28% of 700 = 196
    Total no of cars in state 3 = 32% of 700 = 224
    Total no of cars in state 4 = 26% of 700 = 182
    Number of petrol engine cars in state 1 = 98 * 4/7 = 56
    Number of petrol engine cars in state 2 = 196 * 9/14 = 126
    Number of petrol engine cars in state 3 = 224 * 3/8 = 84
    Number of petrol engine cars in state 4 = 182 * 1/2 = 91
    Average total number of petrol engine cars in all states = (56 + 126 + 84 + 91)/4 = 89.25
