Question
40% of ‘s’ along with 60% of ‘t’ makes a total
of 200. If ‘t’ is 70 more than ‘s’, then calculate (2s – t).Solution
ATQ,
Given: 0.4s+0.6t=200 t=s+70 Find: 2s−t Substitute t=s+70 into the first equation: 0.4s+0.6(s+70)=200 0.4s+0.6s+42=200 s+42=200⇒s=158 Find t=s+70=158+70=228 Find 2s−t 2s−t=2⋅158−228=316−228= 88
