4. The apples bought by Neetu was of weight 3 ¾ kg and the apples bought by Naren was of weight 2 ½ kg. Who bought more apples and by how much more did it weigh?

5/4kg

Step-by-step explanation:

Given data

Weight of apples bought by Neetu=  3 ¾ kg

Weight of apples bought by  Naren=  2 ½ kg

From the numbers/weights above, Neetu bought more apples

=3 ¾ kg to simple fraction

= 15/4 kg

=2 ½ kg kg to simple fraction

= 5/2 kg

The difference is

=15/4-5/2

=15-10/4

= 5/4kg

Hence  Neetus Apples is 5/4kg morethan Narens Apples

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
