Step-by-step explanation:
We know that LCM×HCF=Product of two numbers, therefore, we have,
7a×7b=(7×140)
⇒49ab=7×140
⇒ab=
49
7×140
⇒ab=20
Two co-primes with product 20 are 4 and 5.
Therefore, the required number is (7×4,7×5)=(28,35)
The sum of these numbers is 28+35=63
Hence, the sum of the numbers is 63.
