the LCM of two numbers is 14 times their HCF the sum of LCM and HCF is 600 if one number is 280 then find the other number

Answer»

Hii There!!

Given that : HCF+LCM= 600, ONE NUMBER= 280

=)LET the HCF be= x

LCM= 14X

HCF+LCM= 600

X+ 14x=600

15x= 600

x= 600/15

x= 40

HCF= 40

LCM = 14x= 14× 40= 560

Since, HCF×LCM= Product of two numbers

40× 560= 280× 2nd NUMBER

2nd NUMBER= (40×560) /280

=) 40×2

= )80.


So, 2nd NUMBER =) 80.

Cos58/sin32-root3cos38cosec52/tan15tan60 tan75

Answer»

Ans. 0

\frac{ \cos(58) }{ \sin(90 - 58) } - \frac{ \sqrt{3 } \cos(38) \ \csc (90 - 38) }{ \<klux>TAN</klux>(90 - 75) \tan(60) \tan(75) }
We know that Sin(90-x)=COSX
Cosec(90-x) = Secx
Tan (90-x) = COTX
\frac{ \cos(58) }{ \cos(58) } - \frac{ \sqrt{3 } \cos(38) \sec(38) }{ \ \cot(75) \sqrt{3} \tan(75) }
Using, Cosx × Secx =1
and Cotx × TANX =1
1 - \frac{ \sqrt{3} }{ \sqrt{3} }
= 0

Find the least number of 5 digit that exactly divisible divisible by 16 18 24 and 30

Answer»

Hye

=======================

let us FIND the lcm 0f  16 18 24 and 30
=>PRIME facoristaion of 16 = 2*2*2*2

     prime facoristaion of 18 = 2*3*3

prime facoristaion of 24 = 2*2*2*3

prime facoristaion of 30 = 2*3*5

common facotors are  2,2,2,2,3,3,5

=>2*2*2*2*3*3*5 = 720

------------

Least Number of 5 digit=10000

Nowlets  divide 10000/720

=13.88

14[rounded off]

so answer = 14*720
