Very hard help me.......

Solution:

Points scored for hitting the target = (+5)
Points scored for missing the target = (-2)

Number of times Ramesh hit the target = 5
So, Points scored = 5 × (+5) = 25
Number of times Ramesh missed the target = 7
So, Points scored = 7 × (-2) = -14
Therefore, total points = 25 - 14 = 11

Number of times Rakesh hit the target = 9
So, points scored = 9 × (+5) = 45
Number of times Rakesh missed the target = 11
So, points scored = 11 × (-2) = -22
Therefore, points scored = 45 - 22 = 23

Thus, product of their points = 11 × 23 = 253
