In the first Q the hcf and lcm of two numbers are 12 and 20 respectively. Give that one of the number is 6. It's known that a number is always divisible by it's hcf. Since 6 is not divisible by hcf(i.e 12) so Q is wrong conceptually. Theory - Any factor always divides the number and hcf is highest factor.
Step 1: Let's assume the mixture has a total of 5 grams (2 grams gold + 3 grams silver) to match the ratio. Step 2: Calculate the total cost of the mixture: 5 grams * Rs. 2350/gram = Rs. 11750 Step 3: Calculate the total cost of gold in the mixture: 2 grams * Rs. 3400/gram = Rs. 6800 Step 4: Calculate the total cost of silver in the mixture: Total cost of mixture - Total cost of gold = Rs. 11750 - Rs. 6800 = Rs. 4950 Step 5: Find the price of silver per gram: Rs. 4950 / 3 grams = Rs. 1650 per gram Therefore, the price of silver per gram is Rs. 1650.

hlo sir In the first question if we go through answer 6,40 but lcm of these are 120 where hcf is 2 the relation is satisfying but the given data is wrong

Hey Everyone👋,
Here is the updated Deloitte NLA Preparation Course for 2025 Hiring: prepinstaprime.com/syllabus/deloitte-nla-syllabus
In the first Q the hcf and lcm of two numbers are 12 and 20 respectively. Give that one of the number is 6.
It's known that a number is always divisible by it's hcf. Since 6 is not divisible by hcf(i.e 12) so Q is wrong conceptually.
Theory - Any factor always divides the number and hcf is highest factor.
HCF LCM NUMBER - 3:40
E & F - Work Done 12 Days - 5:20
Successive Discount - 12:30
Get Time Years for Simple Interest - 15:00
Streams and boat answer is wrong. Correct answer will be 9.
5 = (40/20+x) + (40/20-x)
5(20^2 - x^2) = 1600
x = 8.94 ~ 9
Yes for me as well its coming like this
It's wrong u forgot to multiply the LCM! to the numerator on the RHS
@@Tan_cannon I didn't get it. Can you share the solution?
@@sanikamhatre5 = ((40*(20-x))/20+x) + ((40*(20+x))/(20-x)) now solve
yes same for me as well
Step 1: Let's assume the mixture has a total of 5 grams (2 grams gold + 3 grams silver) to match the ratio.
Step 2: Calculate the total cost of the mixture:
5 grams * Rs. 2350/gram = Rs. 11750
Step 3: Calculate the total cost of gold in the mixture:
2 grams * Rs. 3400/gram = Rs. 6800
Step 4: Calculate the total cost of silver in the mixture:
Total cost of mixture - Total cost of gold = Rs. 11750 - Rs. 6800 = Rs. 4950
Step 5: Find the price of silver per gram:
Rs. 4950 / 3 grams = Rs. 1650 per gram
Therefore, the price of silver per gram is Rs. 1650.
About the dress problem, It is easier just to multiply remains like so:
800*0.8*0.9=576
I never knew that 12 is a factor of 6 rather than a multiple. I also didn't know that 40 is fully divisible by 6. Thanks for teaching me.

hlo sir
In the first question if we go through answer 6,40 but lcm of these are 120 where hcf is 2
the relation is satisfying but the given data is wrong
@prepinsta yes bcause hcf itself should be a factor of lcm values are wrong in first question

I couldn't understand ques no 8.
Question no. 1 is wrong it's not framed correctly
5x -3x =20, x=10, 50*30 = 1500
How many questions do i need to answer correct to go into next round
Q1 will be 12 and 2 instead of 12 and 20!
