Which of the following statements is INCORRECT?

A Kusum buys some chocolates at the rate of ₹ 10 per chocolate. She also buys an equal number of candies at the rate of ₹ 5 per candy. She makes a 20% profit on chocolates and 8% profit on candies. At the end of the day, all chocolates and candies are sold out and her profit is ₹ 240. Therefore, Kusum buys 100 chocolates.
B A carpenter charged ₹ 2500 for making a bed. The cost of materials used is ₹ 1100 and the labour charges are ₹ 200/hr. So, the carpenter will work for 7 hours.
C On dividing ₹ 200 between A and B such that twice of A's share is less than 3 times B's share by 200. So, B's share is ₹ 120.
D Madhulika thought of a number, double it and added 20 to it. On dividing the resulting number by 25, she gets 4. Hence, the required number is 45.

(C): Square + square+ square+ square+ square = 125

⇒ 5 × square = 125
⇒Square = 25
Now,


⇒Star × star = 25
So, Star = 5
Hence, Star + star + square + square = 5 + 5 + 25 + 25 = 60

The solution proves that option B is the correct answer but shows option A as the correct answer, which is wrong. Please fix this mistake.

Ans 2:

Class : Class 8
The explanation is not reflected in the answer. The explanation shows option B to be correct, but answer is marked as option A. If this is a representation of the actual exam, 1-2 years later no one would give it. This is a serious blunder occurring multiple times in the website. We did not pay to get these terrible errors. Please fix this.

Ans 3:

Class : Class 9
complete blunder as sharanyaa saidPLEASE FIX ITDON'T CUT OUR MARKS FOR SUCH TECHNICAL ERRORS

Ans 4:

Class : Class 8
When even in the solution the answer is II is correct then why in the correct answer it shows the option which says I is correct? This is an absolute blunder. Please fix it, SOF.

Ans 5:

Class : Class 8
According to the solution itself, Statement 1 is false while Statement 2 is true. i have checked it by solving the questions myself and it is correct. The question says,"Which of the following statements is CORRECT?" They have asked for the CORRECT statement, not the INCORRECT one. Therefore, the answer will be Option B, not Option A. SOF, PLEASE RECTIFY THESE ERRORS WHICH KEEP OCCURING FREQUENTLY IN MANY TESTS.

Ans 6:

Class : Class 8
If statement 2 is true, then B should be answer wat.
