bhai plz give the ans of following qn attached below......plz dont forget to explain the method thank u

3810

bhai log.. plz help me with the method.. If x= sqrt(3)/2 then find sqrt(1+x) + sqrt (1-x)

3811

b is my take

@ js-m please tell right ans

bhai use formula (root 1+x + root 1-x ) ^2 = ( 1+x + 1-x + 2root ( 1-x^2) ) and get the ans
3814
@VENRAG there is a direct formula for this
difference =P(r/100)^2(r/100+3)

yr ye formula kitne years ka hai and baad wala sab power me hai kya??
3818
@pathakrahul its B and A respectively
3819
@masuka123  LET WAT IS ASKED EQUAL TO Y SQUARE BOTH SIDES AND PUT VALUE OF X U GET ROOT3

it is only for three years ssc won;t go beyond that....r/100 wala hi square hai..
3822
@sumit1234567890 yaar ssc mei kabhi instalments ka sawaal aaya hai kya in si and ci problms?

B)360deg*3.5 in 1 sec

so, 57.2deg[ because of 180deg/3.14]*55 deg in = 57.2*55/(360*3.5)= 2.5sec


A)(63+14/60 +51/360) deg

180 deg = pi

so (63+14/60 +51/360) deg = (63+14/60 +51/360)/180= .35pi = 2811pi/8000
3824
@harsh1839 value of each installment wale aaye hai....
3825

koi questions post karo ....bhai

3826

gyz can anyone privide me the link of the question paper of the exam on 15th??????

That is paper 3...........plz.........asap

the area of a circle whose radius is 8 cm is trisected by two concentric circles the ratio of radii of the concentric circles in ascending order is


bhai plz elaborate it again i am having some dufficulty in assimilating this solution


let radius of circle be a,b,c in increasing order then;

pie a^2 = pie( b^2-a^2)

2 a^2 = b^2;------(1)

pie ( c^2 -b^2) = pie ( b^2 - a^2)

a^2 + c^2 = 2 b^2;------(2)

sub (1) in(2); also c=8 given

a^2 + 64 = 4 a^2

a=8/rt3; sub in (1)

b=(rt2 * 8)/rt3;

c=8;

8;(8/rt3);(rt2*8)/rt3= 1:rt2:rt3




this solution has given by one of the guy of pg

a sum of Rs 10000 is borrowed at 8% p.a comppounded annually which is paid back in 3 equal installments... wat is the amnt of each installment?? plz xplain step wise
