Suppose the functions F and G can be computed in 8 and 3 nanoseconds by functional units UF and UG, respectively. Given three instances of UF and three instances of UG, it is required to implement the computation F(G(Xi)) for 1 ≤ i ≤ 13. A control Unit selects next task/s and ... complete this computation is ( in nanoseconds): (A) 28 (B) 33 (C) 43 (D) 49 my answer is 43 but gatebook answer is 49.

Consider a program being run on a processor. A modification in processor design caused 30% of the program to speed up by ten times while three fourth of the remaining program has a speed up of 80 and 40% of the remaining part of the program performs poorer and looses its speed by 50%. The remaining program has a speedup of 1. The overall speedup of the program exact to two decimal places is:—
