B) TFTF
C) TTFF
D) FFTT
Correct Answer: D
Solution :
\[63(3\times 3\times 7)\] and \[81(3\times 3\times 3\times 3)\] are multiples of 9 but \[77(7\times 11)\]is not a multiple of 9. \[49(7\times 7)\] and \[63(7\times 3\times 3)\] are multiples of 7 but\[88(2\times 2\times 2\times 11)\]is not a multiple of 7. 2, 5 and 8 are factors of\[40(1\times 2\times 2\times 2\times 5)\] 3, 6 and 13 are factors of\[234(1\times 2\times 3\times 3\times 13)\]You need to login to perform this action.
