Suppose the ‘number’ of fours is x and y is the number of sixes. Then we get,
100= 4x+6y+16
84= 2(2x+3y)
42= 2x+3y. Call this equation 1
From the information we know,
y= x/2
2y=x. Call this equation 2
substitute this value into the equation 1 and we get,
42= 2*2y+3y
42= 7y
y= 6
Back to equation 2 we get,
2*6=x
12=x
Therfore, Sachin hit 12 fours and 6 sixes
100= 4x+6y+16
84= 2(2x+3y)
42= 2x+3y. Call this equation 1
From the information we know,
y= x/2
2y=x. Call this equation 2
substitute this value into the equation 1 and we get,
42= 2*2y+3y
42= 7y
y= 6
Back to equation 2 we get,
2*6=x
12=x
