A Correct answer
AI explanation

The initial total cost for the 100 toys is Rs. 46 multiplied by 100, which equals Rs. 4600. The correct prices were Rs. 43 and Rs. 16, summing to 59, but they were read as Rs. 34 and Rs. 61, which sums to 95. This means the total cost was understated by 95 minus 59, or 36 rupees, making the corrected total 4600 plus 36, which is 4636. Dividing this new total by 100 gives the new average cost of Rs. 45.60.
