Explanation

P is 5 time large as Q 

p=5q

q =p/5

The percentage that q is less than p=p-q/p*100

=(1-1/5)*100

=4/5*100=4*20

=80%

Explanation

Explanation

Hence, we get the number is 100.

Explanation

27 baskets / 15 men = 1.8
So, 1 man can make 1.8 baskets in an hour.

1.8 baskets / 60 minutes = 0.03
So, 1 man can make 0.03 baskets in a minute.

0.03 baskets × 40 minutes = 1.2
So, 1 man can make 1.2 baskets in 40 minutes.

1.2 baskets × 45 men = 54
S0 45 men can make 54 baskets in 40 minutes.

Explanation

Let 

spring =A 

Summer=B 

A+B=85

A=4B

4B+B=85

5B=85

B=85/5=17

A=4*17=68

Explanation

Let the son's current age be x.

The mother's current age is 3x (since it's 3 times the son's age).

After 8 years, the son's age will be x + 8.

After 8 years, the mother's age will be 3x + 8.

Now, let's assume the son's current age is 10 (x = 10). Then:

The mother's current age is 3x = 3(10) = 30.

After 8 years, the mother's age will be 30 + 8 = 38.

Explanation

Let's break down the movements step by step:

East 10 meters:

You are now 10 meters east of your house from the starting point.

North 15 meters:

Now you're 10 meters east and 15 meters north of your house.

West 12 meters:

Moving west by 12 meters puts you 2 meters west of your house (because 12 - 10 = 2).

South 15 meters:

Moving south 15 meters brings you back to your house's north-south position (because 15 meters north - 15 meters south = 0).

So now you're 2 meters west and 0 meters north-south from your house.

The distance from your house is simply 2 meters.
