A figure with 1,2,3,4 forming a sqaure

2 is 1/2 of the 50%

3 is 1/2 of the 50%

1 is 3/4 of the 50%

4 is 1/4 of the 50%

B has 5/8 of the figure

Adding the fraction of 1 and 2 or 1 and 3

(1/4 of 50%) + (3/4 of 50%)

= 25% + 37.5% = 0.25 + 0.375

                          = 0.625

                          = 625/100

                          = 5/8

So the answer is (1) 1 and 2
