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

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

Ans 2:

Class : Class 8
complete blunder as sharanyaa saidPLEASE FIX ITDON'T CUT OUR MARKS FOR SUCH TECHNICAL ERRORS

Ans 3:

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 4:

Class : Class 8
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 5:

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.
