Final answer:
Harilal spent 85% of his total money leading to a remainder of Rs. 1305, which is 15% of his initial amount. Calculating back, Harilal's initial amount was Rs. 8700, which does not correspond with any given options, indicating an error in the question or options.
Step-by-step explanation:
The question presents a scenario where Harilal spent a certain percentage of his money on various expenses and is left with a balance of Rs. 1305. To find the total money Harilal initially had, we consider the total percentage spent and the remaining balance.
According to the question, Harilal spent 40% on machinery, 25% on building, 15% on raw material, and 5% on furniture. In total, this amounts to 85% spent (40% + 25% + 15% + 5%). Remaining balance is thus 15% of the total money Harilal initially had.
Let the total money be 'x'. If 15% of 'x' equals Rs. 1305, then 0.15x = 1305. To find 'x', we divide both sides of the equation by 0.15, which gives us x = 1305 / 0.15, which calculates to Rs. 8700. Therefore, Harilal initially had Rs. 8700.
To find out the option that matches his total money, we do not need to calculate further as none of the given options (Rs. 2000, Rs. 2200, Rs. 2400, Rs. 2500) are correct, suggesting there may be an error in the question or the options provided.
