What will come in place of question mark (?) in the following questions:
$$32\cdot05$$% of 259.99=?
92
88
78
90
83
The problem can be solved quickly by rounding off,
32.05% ~32 and 259.99~ 260
Now, 32% of 260 = 83.2
$$\frac{1}{8} of \frac{2}{3} of \frac{3}{5}$$ of 1715=?
80
85
95
75
Now, $$\frac{1}{8} of \frac{2}{3} $$= (1/8)*(2/3)=1/12
Also, ( $$\frac{1}{8} of \frac{2}{3}$$ ) of $$\frac{3}{5}$$ = (1/12) * (3/5) = 1/20 Now, (1/20) 0f 1715= (1/20)*1715 = 85
$$25\cdot05\times123\cdot95+388\cdot999\times15\cdot001=?$$
900
8950
8935
8975
8995
Here we are approximating 25.05~25, 123.95~124, 388.99~389, 15.001~15.
The question can be rewritten as,
25*123+388*15=8935 Hence the correct option is 8935.
$$561\div35\cdot05\times19\cdot99$$=?
320
330
315
325
335
By approximating 561~560, 19.99~20 and 35.05~ 35 for easier calculation,
the question can be written as,
560*(20/35)=320
$$(15\cdot01)^{2}\times\sqrt{730}=?$$
6125
6225
6200
6075
6250
The question can be reframed as,
$$15^{2}$$*$$\sqrt(729)$$=$$225\times27$$=607
In each of these question a number series is given.In each series only one number is wrong.Find out the wrong numbers
3601, 3602, 1803, 604, 154, 36, 12
3602
1803
604
154
36
In the given series, nth term is obtained by - (Previous term/(n-1) ) +(n-1).
Hence the 5th term should be (604/4)+4 = 155.
However 5th term is given as 154. Hence, 154 is wrong term in the given series.
4, 12, 42, 196, 1005, 6066, 42511
12
42
1005
196
6066
In this question, the nth term is obtained by (previous term*n + n^2).
Hence, after 12, the number would be (12*3+9)= 45
Therefore, the correct option is 45.
2, 8, 12, 20, 30, 42, 56
8
30
20
Here the consecutive difference between the terms is incremented by 2 for the series.
Hence, after 2, the number should be 6.
32, 16, 24, 65, 210, 945, 5197.5
945
16
24
210
65
Here the sucessive numbers are multiplied by .5,1.5.2.5....
Hence, in place of 65 the number should be 24*2.5=60.
Therefore, the incorrect number for series is 65.
7, 13, 25, 49, 97, 194, 385
13
49
97
194
25
Here, in this series, the nth term is (previous term + 6*2n-2 )
Hence, in place of 194 the term should be (97+6*24) = 193
