10 . There is a certain amount from which A takes 25%, then B takes 50% of remaining amount, then C takes 75% of the remaining amount. Now if the amount left is 5760, then what is the actual sum?

 A.   Rs.58220 B.   Rs.59680 C.   Rs.59680 D.   Rs.61440

1 .

 Answer : Option C Explanation : Total construction in Q = 100 + 175 + 275 = 550Total construction in T = 175 + 250 + 300 = 725∴ Required difference = 725 – 550 = 175
2 .

 Answer : Option A Explanation : Average of building demolished=$50+175+150+75+175\over5$ =$625\over5$ = 125
3 .

 Answer : Option C Explanation : Required percentage= $Total number of buildings constructed\over Total number of building redeveloped$ × 100 = $1100\over1400$ × 100 ≈79%
4 .

 Answer : Option D Explanation : Average number of construction in CityR = $150+225+250\over3$ = $625\over3$ ≈ 208
5 .

 Answer : Option C Explanation : Required ratio = $175\over300$ = $7\over12$=7:12
6 .

 Answer : Option C Explanation : The pattern of number series is as follows Hence, the wrong number is 38.Right number = 12 × 3 + 3 = 36 + 3 = 39
7 .

 Answer : Option A Explanation : The pattern of number is as follows Hence, the wrong number is 56Right number = 32 + $(5)^5$ = 32 + 25 = 57
8 .

 Answer : Option D Explanation : The pattern of number series is as followsThis is a prime number series.Hence, the wrong number is 80.Right number = 59 + 19 = 78.
9 .

 Answer : Option D Explanation : The pattern of number series is as follows So, the wrong number is 32Right number = 9 × 2 + 2 × 6 = 18 + 12 = 30
10 .

 Answer : Option D Explanation : Required amount= $Leftamount×100×100×100\over(100 – A)(100 – B)(100 – C)$ = $5760×100×100×100\over75×50×25$ = 61440
