7. 5; The number of girls good at cooking = 7800 × 35% = 2730 The number of girls good at
(i) cooking and studies = 2730 × 20% = 546
(ii) cooking and dancing but not in studies = 2730 × 30% = 819
Hence, the number of girls good at cooking only is either equal to or less than (2730 - 546 - 819 =)1365.


8. 5; The number of girls good at drawing = 5% of 7800 = 390


9. 5; Data  inadequate.


10. 1; The number of girls good only at singing = 10% of 7800 = 780
