Actually the right Anwer is A but many children and admin are saying C so the thing is all about 1/5th money 💴 he spended and how much was left after 800 [the 1/5th of 4000] was subtracted from 4000

Ans 3:

Class : Class 8
That's what the spent amount should be subtracted.

Ans 4:

Class : Class 4
A

Ans 5:

Class : Class 6
It is C because he spent one fifth of it so we have to add 800 because he earnt it.It is showing in the chart after he spent the money.

Ans 6:

Class : Class 6
Ans should be A. 4000 has been added with 800 instead of subtracting them.

Ans 7:

Class : Class 4
D

Ans 8:

Class : Class 4
Ans should be A

Ans 9:

Class : Class 7

Ans 10:

Class : Class 5

Ans 11:

Class : Class 4
ans should be A

Ans 12:

Class : Class 2
ans is a because 4000 -800 is 3200

Ans 13:

Class : Class 5
The correct answer is 'A.3200' as he is spending one-fifth of the money in April then we have to subtract one-fifth of he amount(Rs.4000) he is having and when we subtract the amount Rs.4000 from Rs.800 the answer we will get is Rs.3200 which is in option 'A'

Ans 23:

Class : Class 4
Question is wrongAnswer is actually 'A'They have added 800 when they had to subtract 800 from 4000Therefore, the answer is actually 3200

Ans 24:

Class : Class 4
Answer is (A) not (C) because we have to -800 not 800 as question says.

Ans 25:

Class : Class 5
answer is a

Ans 26:

Class : Class 4
Earnings cannot be less than savings so the answer is C
