Explanation

The relationship between 4 and 20 is that 20 is 5 times 4.

Similarly, to find the number that corresponds to 5 in the same way, multiply 5 by 6:

4×5=20

5×6=30

Thus, 5 is to 30 in the same way that 4 is to 20.

Explanation

Let the required weight be xkg.Less weight,less cost(DirectProportion)∴250:200::60:x⇒250×x=200×60⇒x=200×60250⇒x=48

Explanation

144/8 = 18 people.

Thus you would need twelve additional people.

Explanation

• SHORT TRICK Percentage of uncertain individuals =[100−(20+60)]%=20% Since, 60% of x−20% of x=720 40% of x=720 100 40​x=720 x= 40 720×100​=1800 Hence the answer is 1800.
