Correct Answer: abab

Solution : Given:

a_ _b abba_abb a_ba

Let's check the given options –

First option: abab
The series becomes aabbabbaaabbabba.

The pattern in the series becomes aa / bb / ab / ba / aa / bb / ab / ba.
Second option: abba
The series becomes aabbabbababbaaba.

There is no pattern in the above series.

Third option: aabb
The series becomes aaababbababbab ba.
There is no pattern in the above series.

Fourth option: aaab
The series becomes aaababbaaabbabba.
There is no pattern in the above series.

Hence, the first option is correct.

Correct Answer: 5 – 25 – 225

Solution : Let's check each option –
First option: 5 – 25 – 225; (5)² = 25; (5)³ = 125 ≠ 225
Second option: 6 – 36 – 216; (6)² = 36; (6)³ = 216
Third option: 9 – 81 – 729; (9)² = 81; (9)³ = 729
Fourth option: 3 – 9 – 27; (3)² = 9; (3)³ = 27

So, only the first option doesn't follow the same pattern as followed by the other options. Hence, the first option is correct.

Solution : Vilas remembers his marriage is after the 4th of July. i.e., on 5th, 6th, 7th, 8th and so on.
His sister remembers his marriage is before the 6th of July. i.e., on 5th, 4th, 3rd, 2nd and so on.

Correct Answer: 18

Solution : Subtract column three from the sum of column one and column two, to get column four –

In row one: 46 + 12 – 30 = 28
In row three: 54 + 10 – 29 = 35
Similarly, follow the same pattern for row two: 32 + 16 – X = 30; X = 18

So, 18 is the required number in the given figure. Hence, the fourth option is correct.

Correct Answer: Haemoglobin

Solution : The correct option is Haemoglobin

The red colour of human blood is caused by a molecule known as haemoglobin. The protein haemoglobin is present in red blood cells and delivers oxygen from the lungs to the rest of the body's tissues and organs. Haemoglobin also aids in the transfer of carbon dioxide, a byproduct of metabolism, back to the lungs for expiration. The red colour of haemoglobin is a result of its iron content. When it binds with oxygen in the lungs, it forms a complex called oxyhaemoglobin, which is bright red.

Correct Answer:  Appreciation of domestic currency

Solution : A flexible exchange rate system is one in which the market's supply and demand for money determine the exchange rate. The value of the currency is free to alter in response to shifts in the supply and demand for foreign currencies under a flexible exchange rate system. Under a flexible exchange rate when the price of domestic currency in terms of foreign currency increases it is called appreciation of domestic currency.

Correct Answer: 0.5

Solution : Given:
$-\frac{7}{4}$, –1, –0.25, ?, $\frac{5}{4}$, 2

First, convert all the fractional values into decimals –
$-\frac{7}{4}$ = –1.75, –1, –0.25, ?, $\frac{5}{4}$ = 1.25, 2
Let's apply the pattern –
–1.75 + 0.75 = –1 ; –1 + 0.75 = –0.25; –0.25 + 0.75 = 0.5; 0.5 + 0 .75 = 1.25; 1.25 + 0.75 = 2

The missing number is 0.5. Hence, the first option is correct.

Correct Answer: XIFGERU

Solution : Given:
OBESITY is written as EBOHYTI. 

Change the position of the first and last three letters and write the opposite letter of the middle letter of OBESITY, to obtain the required code –

Thus, OBESITY is coded as EBOHYTI.
Similarly, follow the same pattern for FIXTURE –

Thus, FIXTURE is coded as XIFGERU. Hence, the first option is correct.
