"A)Rs. 1200",
"B)Rs. 1300",
"C)Rs. 1500",

Let his additional investment at 8% = x
Interest on Rs.x at 8% per annum = ( x × 8 × 1 ) / 100 = 2x/25.
To earn 6% per annum for the total, interest = (3000 + x) × 6 × 1/100.

P (E or H) = P (E U H)

"A)179",
"B)208",
"C)210",
"D)225"
] | D | Explanation:
Total runs scored by the batsman = 62*46 = 2852 runs
Now excluding the two innings the runs scored = 58*44 = 2552 runs
Hence the runs scored in the two innings = 2852 – 2552 = 300 runs.
Let the highest score be x, hence the lowest score = x – 150
x + (x - 150) = 300
2x = 450
x = 225 runs
