Select the option in which the numbers are related in the same way as are the numbers of the following set.
(12, 121, 169)
The pattern in (12, 121, 169) is:
(12, 112= 121, 132= 169) that is (12, 11, 13)
Similar pattern is seen in (17, 256, 324) as:
(17, 162= 256, 182=324) that is (17, 16, 18)
Hence, option B is the correct answer.
Study the given pattern carefully and select the number that can replace the question mark (?) in it.
First row- 6, 39, 124
Second row- 8, 53, ?
Third row- 11, 74, 229
NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 – Operations on 13 such as adding /deleting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is NOT allowed).
The logic here is that the first number is multiplied by 7 and 3 is subtracted from the result to get the second number and the second number is multiplied by 3 and 7 is added to get the third number –
6 × 7 – 3 = 39 and 39 × 3 + 7 = 124
11 × 7 – 3 = 74 and 74 × 3 + 7 = 229
Similarly,
8 × 7 – 3 = 53 and 53 × 3 + 7 = 166
Hence, option D is the correct answer.
Select the correct combination of mathematical signs to replace * signs and to balance the following equation.
105*85*17*9*60
Check option a-
Given expression is-
After interchanging-
105-85÷17 ×9 =60
Solve now,
105-5 ×9 =60
Or, 105-45 =60
Or, 60=60
Hence, option A is the correct answer.
Select the figures form among the given options that can replace the question mark (?) in the following series.
So, the next figure is:
Hence, Option A is the correct answer.
Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements.
Statements:
Some telephones are mobiles.
All mobiles are tablets.
Some tablets are laptops.
Conclusions:
I. Some mobiles are laptops.
II. All telephones are tablets.
III. Some telephones are tablets.
Possible Venn Diagram
I. Some mobiles are laptops. – It is not a definite case, hence false.
II. All telephones are tablets. – It is not a definite case, hence false.
III. Some telephones are tablets. – It is a definite case , hence true.
Only conclusion III follows.
In a certain code, ‘HOME’ is written as ‘41’. How ‘SOFT’ is written in that code?
Hence, option C is the correct answer.
The two given expressions on both the side of the ‘=’ sign will have the same value if two numbers from either side or both side are interchanged. Select the correct numbers to be interchanged from the given options.
6 × 5 – 8 ÷ 2 + 1 = 3 × 4 + 2 + 9 ÷ 3
By checking option A:
6 × 5 – 4 ÷ 2 + 1 = 3 × 8 + 2 + 9 ÷ 3
Or, 30 – 2 + 1 = 24 + 2 + 3
Or, 29 = 29
Therefore, its correct option.
Select the number that can replace the question mark (?) in the following series.
207, 209, 212, 217, 224, 235, ?
Logic is:
207 + 2 = 209
209 + 3 = 212
212 + 5 = 217
217 + 7 = 224
224 + 11 = 235
235 + 13 = 248
Every number that is being added is a prime number
Manyak is the son of Aravind. Manyak and Kashyap are brothers. Durga is the mother of Kashyap. Sanhit is the brother of Aravind. Hruday is the son of Sanhit. How is Hruday related to Kashyap?
As per the given information;
Clearly, Hruday is the cousin of Kashyap.
In a certain code language ‘PSYCHOANALYSE’ is written as ‘! @ #$%^&*&<# @ >’. How will ‘CANALS’ be written in that code?
