Answer (b)
Explanation:
Solution2.
Answer (d)
Explanation:
21^{5.36–3.47} = 21(?)
21^{1.89} = 21?
∴ ? = 1.89
Solution3.
Answer (c)
Explanation:
8^{1.3} × 4^{0.6} × 16^{0.2}
= 2^{3(1.3)} × 2^{2(0.6)} × 2^{4(0.2)}
= 2^{(3.9+1.2+0.8)} = 2^{5.9}
= ? = 5.9
Solution4.
Answer (d)
Explanation:
11/7 + 22/3 + 18/5 = 1313/105
Solution5.
Answer (d)
Explanation:
Solution6.
Answer (b) Explanation: 402 + 713 =1115
1115 + (2 × 713) = 2541
2541 + (3 × 713) = 4680
4680 + (4 × 713) = 7532
Solution7.
Answer (c)
Explanation: Each previous term is divided in the series (4.5, 3.5, 2.5.1.5) to get next term.
Solution8.
Answer (d)
Explanation: From the right hand side, each next term is square of the first term.
Solution9.
Answer (a)
Explanation: 5 × 4 + 4 = 24
24 × 4 + 4 = 100
100 × 4 + 4 = 404
404 × 4 + 4 = 1620
1620 × 4 + 4 = 6484
Solution10.
Answer (b)
Explanation: Each next term, is the cube of consecutive odd numbers starting from 1. The term in place of question mark is 729.
Solution11.
Answer (C)
Explanation: Total no. of votes = 100%
Votes not cast = 10%
Invalid votes = 20%
Valid votes = 90/100 × 80 = 72%
Votes received by winner = 72 × 75/100 = 54%
Votes received by Loser = 72 – 54 = 18%
So, difference = 36% votes = 10800
100% = 10800/36 × 100 = 30,000 votes.
Solution12.
Answer (b)
Explanation: Let the cost price of one gram be Re. 1, then the mark up price be Rs. 1.3 per gram.
Now he sells 1000 gram which seems to be 1250 g which seems to be 1250 g so he charges to a customer 1250 × 1.3 = Rs. 1625 for 1000 g (or Rs. 1000)
Solution13.
Answer (b)
Explanation: Ratio of values of 1 rupee , 50 paise and 25 paise coin is 3/1:4/2:12/4 i. e , 3: 2 : 3 Therefore 3x+2x+3x= 1800
8x = 1800
X= 225.
Value of 50 paise coin = 2 × 225 = 450.
And the number of 50 paise coin s = 450 × 2 = 900.
Solution14.
Answer (c) Explanation: Distance covered in 10 minutes at 20 kmph = distance covered in 8 minutes at (20+x) kmph
20× 10/60 = 8/60(20 + x)
200 = 160 + 8x
8x = 40
x = 40/8 = 5 kmph
Solution15.
Answer (d) Explanation:
Speed upstream= 30* 2/5 (Distance/Time) =12 kmph
Speed downstream= 30* 2/3 =20 kmph
Speed of water current= 1/2*(Downstream speed - Upstream Speed)
=1/2*(20 - 12) = 4 kmph
Solution16.
Answer (C) Explanation: Post of the tank filled in 1 hour
Tank will be filled in 15 hrs.
Solution17.
Answer (b) Explanation: Ratio of the speeds of P and Q.
= P : Q = 2 : 1 = 6 : 3
Q : R = 3 : 1
P : Q : R = 6 : 3 : 1
Ratio of their time taken
1/6 : 1/3 : 1
∴ Time taken by Q
6/2 × 114 minutes
= 38 minutes.
Solution18.
Answer (d)
Explanation: Total number of ways of drawing 2 cards from a pack of 52 cards = 52C_{2} = 52×51 / 1×2 = 26×51
As there are 4 king so number of ways of drawing 1 king from 4 = 4C_{1}= 4
Also there are 4 queens so number of ways of drawing 1 queen from 4 = 4C_{1} = 4
Now the required probability that one of them is king and other a queen = 4×4 / 26×51 = 8/663
Solution19.
Answer (b)
Explanation:
Let P be the sum to be found.
In 3 years, P(1 + r/100)^{3}= 6740 ------ (1)
And, In 6 years, P(1 + r/100)^{6}= 10110------ (2)
Dividing both, we get,
(1 + r/100)^{3} = 10110/6740 = 3/2
Substituting this value in – (1)
P×(3/2) = 6740
P = 4493.33

Solution27.
Answer (c)
Explanation: Investment from Companies E and F is 3% + 7%= 10%
Solution28.
Answer (c)
Explanation: Investments other than A and C= 100-64= 36%
Investments by D and E = 18%
So, Investment by D and E = 18 × (2750/36)=1375 Crores
Solution29.
Answer (d)
Explanation: Ratio of investments of Companies E to D is 3:15 or 1:5.
Solution30.
Answer (a)
Explanation: Each percentage covers 3.6 degrees (360/100).
Percentage of investment of B and d together is 25
So 25 X 3.6= 90 degrees.
Solution31.
Answer (c)
Explanation: Number of employees qualified in the written test
In the year 1992 for promotion in ITC group= 3500
Number of employees qualified in the written test
In the year 1996 for promotion in Tata group = 4000
Required ratio = 3500/4000=7/8=7∶8
Solution32.
Answer (e)
Explanation: Average number of candidates
(3500+4000+4000+5500+5000+6000)/6
=28000/6≈4667
Solution33.
Answer (e)
Explanation: Number of employees in
2002 is 2000 + 3500 = 5500
2003 is 3500 + 4000 = 7500
2004 is 5000 + 4000 = 9000
2005 is 6000 + 5500 = 11500
2006 is 4000 + 5000 = 9000
2007 is 6500 + 6000 = 12500
Hence, 2007 year was the highest amongst all.
Solution34.
Answer (a)
Explanation: Required difference
= (4000 + 5000) – 4000 = 5000
Solution35.
Answer (e)
Explanation: Required number of candidates
(2 + 3.5 + 5 + 6 + 4) × 1000 = 20500.
