this is the correct answer
or
600/13
@yudh said:
bhai batana mera to 600/7 aara hai???


bilkul 600/7% hoga yaar profit on 70 rs

@watsnew24 said:
C price = 70 A = 91& B = 130so 60/70 *100 = 600/7%....?????
bhai
B=100
A=70
c=700/13=>(130/100)*x=70
=>x=700/13

now
[{100-(700/13)}/100]*100=600/13

2) use SIN ( A+B) = sin A cos B+ coa A sin B
3) use sec^2 A - Tan^2 A= 1

4) ISME BATANE KA KUCCH HAI KYA....................

@gudda1122 said: A sells his goods 30% cheaper than B and 30% dearer than C, by what % cost of C's goods cheaper than B's goods??

bhai itna hi fi calci kyu kar raha hai...

by what % C's good cheaper than B me there is only one diffrence in you ka & I ka answer....

u took it with B I took it with C......

Bhai

neeche pehle tan ko cot mein convert kar ke oopar le aao
then use cot( 90 - A) = tan A

are 2nd hua kya? explain plz
5cos + 12sin =13 /... find tan

If X+ 1/4X = 3/2

then find 8X^3 +1/8X^3
4020
@mickym said: If X+ 1/4X = 3/2

21
4021

If X+ 1/4X = 3/2


then find 8X^3 +1/8X^3
4022

If X+ 1/4X = 3/2


then find 8X^3 +1/8X^3
4023

5cos + 12sin =13 /... find tan
tan=sin/cos
12sin=P
5cos=B
P/B=tan
ab bas divide kar do

@mickym 18
4026
@mickym said:
@mickym said: If X+ 1/4X = 3/2
then find 8X^3 +1/8X^3
2X+1/2X=3
cubing both sides
8x^3+1/8x^3+3(3)=27
=18
yaar phele woh 2 se kar diya tha
4027
@mickym said: If X+ 1/4X = 3/2

18 hai bhai...

If x= b+c-2a

y= c+a-2b
z= a+b+-2c

find x^2+Y^2- z^2 + 2xy
