Sir :-1008 ÷1.02=988.235
But in 1008 there is 4 significant figures and in 1.02 have 3 significant figures ... less significant figures value is 1.02 that's why the answer is 988🙂

[@AyushSharma-sr6bg]

thank you sir.

[@-hydraadi-2925]

Sir i have a doubt.
At 6:08
I think if there was 5200 then we can count 2 significant number
& When it was 5200 cm. ( With any physical unit) we have to consider zero in significant number so 4 significant number there.
If i am wrong i apologize sir.

[@EdufineAkash]

Yes,,, I am also confused in this..

[@kajal__sharma695]

Yes there are 4 significant figures

[@jkmvi2525]

Jst keep in mind the golden rule ..nd there are 4 sig. Fig

[@maybe_harshh]

I too had this confusion
But I think Physical Unit and Significant number are two different terms
Don't mix it
In quantity it's 5200 and in Significant concept it has only 2

[@luckydewda8543]

Sir answer is 2.4 after subtraction

[@himanshuacharya215]

[@adity7450]

9:37 ques. - ans. is 2.43

[@juhiselsurekar7485]

Difference between precision and accuracy?

[@girimanchikanti36]

accuracy: how close a measured value is to the actual value
precision:how close are the measured value to each other
for an example if u are given to calculate the weight of a certain object and u took the value three times like 12g,11.5g, 12.5g then its precise and if ur told to take out thevalue of g= 9.8 m/s and ur value is 10 or 9.4 or something then its accurate i hope u understood
