Answers:
6. (2)
7. (4) : Let the Sachin and jatin age be 8x and 11x. Now
1.(2): Total share of B and D together = Rs (5 + 11) x (1668/ (7 – 3))
= Rs 6672
2. (3): 75% of total amount = 55,475 + 28525
= 84000
Hence, total amount = (4/3 x 8400)
= Rs 1, 12,000
3. (5): Ratio of their shares = 42 x 12 : 57 x 8
= 21: 19
Hence, required difference in shares = (21 – 19) x (26000/(26 + 19))
= 2/45 x 26000
= Rs 1300
4. (5): Cost Price = (522 x 378)/2
= Rs 450
5. (4)
6. (2)
7. (4) : Let the Sachin and jatin age be 8x and 11x. Now
= (8x + 10)/ (11x + 10) = 13/16
= 128x + 160 = 143x + 130
=143x-128x = 160-130
= 15x = 30
= x = 30/15
= 2
8. (4) :Total no. of students playing badminton from school ‘A’ = 75 + [ (125×20)/100] = 100
9. (2) : required % =[ (100×195)/225] = 86.67%
10. (3) : required difference = 1/5 [(250-240)+(200-210)+(225-200)+(215-130)+(200-165)]
= (10-10+25+85+35)/5
= 145/5
=29
11. (2) : required % = [175/(175+245+215+130+45)]×100
= (175/810)×100
= 21.60 approx.
12. (1) : Average no. of students playing all the given games from schools = [1/5 (250+200+200+210+125)]
= 985/5
=197
Hence, required difference = 197- 125
= 72
