Hello user

Using unitary method we have..

Solution1...

1500 sheets = 100 NB
So, 1NB = 1500/100
So,12 NB = 15 ×12 = 180
______________________

Solution2..

Total % = Total obtained ,marks / Maximum marks in total × 100

= 243 × 100/300
= 81 %
______________________

Solution3..

20/100 × 700 = 20 × 7 = 140

So, 140 eggs were broken.

Solution4...

1 litre = 1000cm^3

So, let x % of 1 litre is 50cm^3

So, x/100 × 1000 = 50

x = 5 %

So, 5 % of 1 litre is 50 cm^3.


Hope it works
