216 Units = 108000 Mass of metal in lead ore = 12000×80% = 9600 Kg.

1 Unit = 108000/216= 500 Mass of Gold in metal = 5×9600/ 6×100 = 80 Kg.

Therefore, 125 Units= 500×125 = 62,500. Mass of lead in ore = 9600 - 80 = 9,520 Kg.

Hence, the correct option is A. Hence, The correct option is D.

42) Answer: A 45) Answer: D

As per the given data in question, Let, Income of B is 100x then the income of A is 60x.

In 15 litres of the first part, Ratio of income of A and B = 60x : 100x = 3x : 5x

Water = 15×26.66% = 15×4/15 = 4 litres And the expenditure of B is 100y then the expenditure of
A is 75y.
Note: 26.66% = 4/15
The ratio of expenditure of A and B = 3y : 4y,
In 8 litres of the second type of liquid,
According to the question,
Water = 8×25/100 = 2 litres
3x = 4y×80% = 4y×4/5,x : y = 16/15.
The total amount of water = 4 + 2 = 6 litres
As we know that, Savings = Income - Expenditure,
Required % = 6×100/23 = 600/23 %
The income of A and B = 3x : 5x;
Hence, the correct option is A.
A = 3×16 = 48 and B = 5×16 = 80,
43) Answer: C
And the expenditure of A and B = 3y : 4y;
According to the question,
A = 3×15 = 45 and B = 4×15 = 60,
Alcohol = 600×50/100×3 = 100 litres
Now,
Let, X litre of alcohol should be added,
Savings of A = 48-45 = 3 Units &
Then, (100 + X)/(600 + X) = 36/100 = 9/25
Savings of B = 80-60 = 20 Units,
Or, 2500 + 25X = 5400 + 9X
The difference in savings of A and B
Or, 16X = 2900
= 20 Units - 3 Units = 17 Units,
Or, X= 2900/16 = 181.25
17 Units = Rupees 5,100 /- 1 Unit = Rupees 3,00/-
Hence, the correct option is C.
