What value will come in place of question mark (?) in the following question?
?/4 of 3√15625 = 200/? of √4
Verify mobile number to view the solution
?2 = (4 * 200 *√4)/(3√15625)
=4 * 200 * 2/25
= 64 = 82
So,
? = 8
(?/7) * √256 = 128/? of 3√2744
?2 = (7 * 128 * 3√2744)/(√/256)
= 7 * 128 * 14/16
= 784 = 282
So, ? = 28
212 – 641/2 + 12961/4 = ?
212 = 441, 82 = 64, 64 = 1296
?= 441- 8 + 6
= 439
57.14% of 154 + 22.22% of 207 = ?
We note that 57.14% = 4/7, 22.22% = 2/9
So, ? = 154 * (4/7) + 207 * (2/9)
= (7 * 22) * (4/7) + (9 * 23) * (2/9)
=(4 * 22)+(2 * 23)
=134
1056 ÷ 33 = ? + 40
?= 1056 ÷ 33 - 40
= 32 - 40
= -8
What value should come in the place of question mark in the given series?
11, 20, 31, 44, 59, ?
The pattern is as follows:
2 * 5 + 1= 11
3 * 6 + 2=20
4 * 7 + 3= 31
5 * 8 + 4 =44
6 * 9 + 5 = 59
7 * 10+ 6 = 76
2195, 1725, 1327, 995, 723, ?
133 - 2 = 2195
123 - 3 = 1725
113 - 4 = 1327
103 - 5 =995
93 -6= 723
83- 7 = 505
36, 54, 90, 126, 198, ?
18 * 2 = 36
18 * 3 =54
18 * 5 = 90
18 * 7 =126
18 * 11 = 198
18 * 13 =234
5, 19, 47, 89, 145,
5 + 14 * 1 =19
19 + 14 * 2=47
47 + 14 * 3=89
89 + 14 * 4=145
145 + 14 * 5 = 215
value should come in the place of question mark in the given series?
632, 582, 534, 488, 444, ?
252 + 7 = 632
242 + 6 = 582
232 + 5 = 534
222 + 4 = 488
212 + 3 = 444
202 + 2 = 402
