Three gardeners can manage 18 trees in a span of 30 minutes. To find out how many trees one gardener can plant, we see that a single gardener would be able to plant 6 trees within the same duration. It's important to note that time does not decrease. Each gardener performs one-third of the work, yet the time remains constant. If we incorrectly assume 1 gardener could plant 6 trees in 10 minutes, we would be implying that they could complete their portion of the task three times faster.

Answer:

It requires 7.5 gardeners to plant 45 trees in the span of 45 minutes.

Step-by-step explanation:

For 3 gardeners, the time taken to plant 18 trees is 30 minutes.

Let us calculate the planting rate of these 3 gardeners.

Rate= 18 trees/30 minutes

Rate= 2/5 trees per minute

Thus, 3 gardeners equate to a rate of 2/5 trees per minute.

Consequently, a single gardener would represent 2/(3*5) trees per minute.

Hence, one gardener plants at a rate of 2/15 trees each minute.

Now, let’s find out how many gardeners are needed to plant 45 trees in 45 minutes.

As derived, one gardener serves at a pace of 2/15 trees per minute.

X(22 /3)= 2/15*(22.5/3)

Thus, it will require 7.5 gardeners to accomplish the task of planting 45 trees within 45 minutes.

babunello [11817]

Answer: After the withdrawal, Rajan's bank balance will be

6150 RS - 2050 RS = 4100 RS

Step-by-step explanation:

Initially, Rajan had 6000 RS in his bank account about a week ago. This indicates that the initial balance he possessed is 6000 RS.

One week later, he credited 150p RS to his account.

Thus, the current total in his account is

= 6000 RS + 150p RS = 6150 RS.

The following day, he withdrew one-third of his total balance. Therefore, the amount withdrawn is

1/3 × 6150 = 6150/3 = 2050 RS

After the withdrawal, his remaining balance in the bank will be the new total minus the amount withdrawn.

His remaining balance in the bank account post-withdrawal will be

6150 RS - 2050 RS = 4100 RS

PIT_PIT [12445]
In a semicircle, there exist pi radians, whereas a full circle consists of 2pi radians. Since 2pi equals approximately 2*3.14, it results in roughly 6.28 radians in half a circle. The total of 2pi radians corresponds to 360 degrees.
