Question

the sum of hcf and lcm of two numbers is 403 and thier lcm is 12 times their hcf .if one number is 93,them find the another number

Answer 1

124. 
Solution 
12HCF = LCM
LCM + HCF = 403
12HCF + HCF = 403
Solving, HCF = 31 , LCM = 372
Let k be the other number.
LCM x HCF = 93 x k
k = (372 x 31)/93 = 124

Answer 2

Answer:

Number is 124

Step-by-step explanation:

According to the question,

12 H.C.F = L.C.M

LCM + H.C.F = 403

12 H.C.F + H.C.F = 403

13 * H.C.F = 403

H.C.F = 403/13 = 31

Now, apply formula,

LCM x H.C.F = Product of two number

L.C.M * H.C.F = 93 x k

12 * 31 * 31 = 93 * k

k = 12 * 31 * 31 /93 = 12 * 31/3  = 4 * 31 = 124

124 is the another number.
