Q-2 Can Someone Clerify pls

what is your doubt??

sir value depriciate bhi toh horahi hain after 1 year vo 9500 hi reh jaayegi right

lekin depriciation se kya farak padta hai.. jis cost pe usne buy kiya, wo to same hi rahega,, that is extra value given in the ques.. uska use nhi hoga

And sir question 4 main answer mera 5 aaraha why in equation apne divide by 2 kiya hain?

that is upstream and downstream speed

U= (x-y)/2

D=(X+Y)/2

sir but stream ki speed 1 or boat ki speed 5 hain naa

toh directly upstream 5-2=3 or downstream 5+1=6 nahin hoggi

ques me diya hai ki upstream jate tym, stream ki speed double ho jati hai

sir thats why sir 5 se maine 2 minus kiya hain

@surajskt:disqus pls carify

yes telling

yes, i just used the wrong formula.. division by 2 is not needed, ur approach is correct

thanks sir pls can you post one quiz of puzzles and DI Daily because your pdf which you have provided is awesome pls post regular 1 DI and Puzzle

ok will try

and without division by 2.. answer is 5 hour

yes sir mera bhi 5 hi aaraha hain and 9th question will you explain once

thanks @surajskt:disqus sir and sir sectional test will be updated weekly basis ??

@surajskt:disqus sir Q-9 pls can you explain

pls explain q6 ..very confusiing…

You can use this direct formula in case of True value and false value

(100+G%)/(100+c%)=True Value/False Value

WHere c= percent gain due to marking the selling price above cost price, here it is 10%

G% = total profit due to this 10% gain and due to false weight.. here we have to find G
