Direction (6-10) :
6) Answer: c)
Required percentage = [(120+160)/(120+240)]*100
= (280/360)*100
= 77.78%
7) Answer: d)
Required difference = (200+150+100+120+240) – (120+200+160+180+100)
= 810–760
= 50
8) Answer: e)
Required ratio = (150/100) * (200+160):(75/100) *(100+240)
= 2 *(360): 340
= 360: 170
= 36: 17
9) Answer: a)
Required percentage
= {[(200+100+120)-(200+160+100)]/(200+160+100)}*100
= (420-460)/460*100
= (40/460)*100
= 8.69%
10) Answer: c)
Required average = (120+200+160+180+100+200+150+100+120+240)/2
= 1570/2
= 785
