Hello sir!!
Actually, In 4th question
Sir you have done a silly mistake [ a=20 ]
20:13 Here, sir you didn't put minus sign
( a= -20). As a result answer is wrong. In book the answer is 5040.


But sir because of your conceptual knowledge, I have tried this sum,
And I get the correct answer 5040.



Thank you sir for your hardwork...

Sir in 4 th question
We have to add of that two equations
a+18d =52
+a+37d=128
=2a+55d=180
Then use formula oa Sn
at last
2a+55d=180
= 28×180
.`. Sn =5040

Sir, aapse thodi si mistake hui hai 4th sum mein lekin kuch nahi aap bhi human ho. Aapke wajah se hi mujhe ye chapter aata aur mein correct solve kar paya ❤

[khushishaikh]

Sir aap kitne acche ho, kitne acche se explain karte ho ☺️☺️

[bluwie_pixx.]

Sir, in 4th question, you've written a = 20 ; the ans is a = --20, since by solving it, Sn=n/2 [2a + (n-1) d] we get answer 5040.
