Jiya Ray 2 years, 7 months ago

First we will take out prime factors of both numbers that is 336 and 54 .. 336=2⁴×3×7 , 54=2×3³ now we know that HCF= product of common terms with lowest power so we multiply 2×3=6 and now LCM = product of prime factors with highest power so we multiply 2⁴×3³×7=3024. And now We will verify so LCM×HCF=product of two numbers 3024×6=336×54 18144=18144.

4x + 3y = 17 { decimals will be removed 4/10x + 3/10y = 17/10 ( here, all the 10 will be cancel out) } ----(i) Similarly: 7x - 2y = 8 will be form by removing decimals in the same manner .----(ii) From equation --(i) ------> X = 17-3y/4 Putting value of x in 7x - 2y = 8 7(17-3y/4) - 2y = 8 119 - 21y/4 - 2y = 8 (by solving brackets) 119 - 21y - 8y /4 =8 (by taking LCM.) 119 - 29y /4 = 8 119 - 29y = 32 ( by multiplying 4 on the left hand side) - 29y = 32 - 119 -29y = - 87 ( subtract sign will be cancled ) y = 87/29 y = 3 Now finding value of x X = 17 - 3y /4 X = 17 - 3(3)/4 X = 17 -9 /4 X = 8 /4 X= 2

Rudra Pratap Singh 2 years, 7 months ago

We have a and b are two odd positive integers such that a & b but we know that odd numbers are in the form of 2n+1 and 2n+3 where n is integer. so, a=2n+3, b=2n+1, n∈1 Given ⇒ a>b now, According to given question Case I: 2 a+b = 2 2n+3+2n+1 = 2 4n+4 =2n+2=2(n+1) put let m=2n+1 then, 2 a+b =2m ⇒ even number. Case II: 2 a−b = 2 2n+3−2n−1 2 2 =1 ⇒ odd number. Hence we can see that, one is odd and other is even.
