Solutions:
- (1) Total no. of qualified candidates from institutes P, Q and R together
= 8000 × (16 + 20 + 16100)
= 8000 × 52100 = 4160
Total no. of appeared candidates from institutes S, T and U together
= 36000 × 15 + 10 + 25100
= 36000 × 50100 = 18000
Required ratio = 4160 : 18000 = 52 : 225
- (5) No. of qualified candidates from institute
T = 8000 × 12100 = 960
No. of appeared candidates from institute
T = 36000 × 10100 = 3600
Required% = (9603600 100 )% = 26.66%
- (2) Total of qualified candidates from institutes Q and R together
= 8000 × 20 16 100
= 8000 × 36100 = 2880
Total no. of appeared candidates from institutes Q and R together
= 36000 × (18 + 20100)
= 36000 × 38100 = 13680
Required % = (288013680 100) % = 21.05% 21%
- (1)
- (3) Total no. of appeared candidates from institutes P, Q and U together
= 36000 × (12 + 18 + 25100)
= 36000 × 55100 = 19800
Required average = 198003 = 6600
- (5)
- (3)Let expenditure of Company A in the year 2015 = Rs100
Income = 100 × 140100 = Rs140 and
expenditure of Company A in the year 2016 = Rs140
Income = 140 × 150100 = Rs210
Required ratio = 140 : 210 = 2:3
- (3)
- (2) Expenditure of Company A in the year 2011 = Rs40 crore
Income = 40 × 120100 = Rs 48 crore
- (4)
