SSC MTS 2019 Question Paper Shift 2 (Aug 19th)

Question 70

If $$u + v = 84$$ and $$u - v = 4$$, then $$u : v$$ is equal to:

Solution

u + v = 84    Eq.(i)

u - v = 4    Eq.(ii)

Add Eq.(i) and Eq.(ii)

u + v + u - v = 84+4

2u = 88

u = 44

Put the value of 'u' in Eq.(ii).

44 - v = 4

v = 44-4

v = 40

So u : v = 44 : 40

= 11 : 10
