Final answer:
Manoj used 40% of the 150 kgs of organic manure he bought, which amounts to 60 kgs. Therefore, he has 90 kgs of manure remaining.
Step-by-step explanation:
To solve the mathematical problem completely, first we need to calculate the amount of manure that Manoj used in his kitchen garden.
Manoj bought a sack of organic manure weighing 150 kgs. He used 40% of it for his garden, so:
- The amount used is 40% of 150 kgs
- To find 40% of 150, you multiply 150 by 0.40 (which is the decimal equivalent of 40%)
- 150 kg * 40/100 = 60 kg
Therefore, Manoj used 60 kgs of manure.
Next, to find out how much manure is remaining, subtract the amount used from the total weight of the manure initially bought:
- Total manure initially = 150 kgs
- Manure used = 60 kgs
- Manure remaining = Total manure initially - Manure used
- Manure remaining = 150 kgs - 60 kgs = 90 kgs
So, Manoj has 90 kgs of manure remaining for his use.
