Objections in the LCT Answer Key
49. I _______ for home tomorrow.

(1) leave

(2) have left

(3) had left

(4) will leave

Both options (1) and (4) are correct as Present tense is used for planned future actions and the word 'tomorrow' suggests that the action is planned and hence future tense can also be used. Both the above mentioned usage are published in oxford dictionaries.

Corrections in the MAT Paper

Q	Answer uploaded on Website	Correction Required
6	4	Option 2 & 4 both are correct.
8	4	Option 1 & 4 both are correct.
44	2	Option 2 & 4 both are correct.
45	1	Option 1 & 2 both are correct.
47	3	Options don't match.

Reasoning for Corrections

6) Option (2) is also correct.The sum of the digits at unit's place and hundred's place is equal to the digit at the ten's place. 

So, in option (2) 891 is given. Here, 8 +1 =9.

8) opposite vertices are joined. With this logic option (1) is also correct.

44) When we take sum of the digits of all the numbers, the question becomes

16 : ? :: 20:18.

So, 20 is 2 more than 18. Similarly, option should have the sum of the digits as 14. 

Here, option (4) is also correct.

45) 13 : 19 : : 31 : ?

Here, clearly 13 +6 =19. Similarly, 31 +6 =37.

So, option (2) is also correct.

47) The options don't match. 

Corrections in the LCT Paper (English Paper)

For Q. 48, Q.49 & Q. 50

The directions for the three questions (q.48, q.49 & q. 50) were missing in the question paper, hence it was not clear on what basis the options were to be chosen, so these three questions should be given bonus.

Objections in the SAT Paper (English Medium)
Q.77.
It should be BONUS
there is a difference between Marathi Medium paper and English Medium paper
In the Marathi Medium paper option (1) is Creditor and Option (4) is Debtor
In the English Medium paper option (1) is Debtor and Option (4) is Creditor
Official answer key says Option (4) i.e. Debtor is correct
but in the English Medium Paper the same option i.e. Option (4) becomes Creditor
Hence this question should be termed as BONUS

Q.83.

It should be BONUS

Explanation - The question asks about expenditure occurred on education, which is represented in the pie diagram. But the Expenditure inccurred on House rent is not shown in the pie diagram. So by the given information, answer cannot be worked out
