Answer & Explanation
16. 48
MULTIPLE OF 6= 6,12,18,24,30,36,42,48,56,72
MULTIPLE OF 8= 8,16,24,32,40,48,56,64,72
Find the same number that both multiples of 6 and 8 contain.
48 is the same number. Check if it is higher than 42 and less than 52.
42<48<52
That is why this is the answer.
48 meets all the conditions given in the question.
17. 35
FACTOR OF 70= 1,2,5,7,10,14,35,70
Find the number that is higher than 30 but less than 40.
30<35<40
18. 18
FACTOR OF 90= 1,2,3,5,6,9,10,15,18,30,45,90
MULTIPLE OF 6= 6,12,18,24,30,36,42,48,54
MULTIPLE OF 9= 9,18,27,36,45,54,63,72,81
Find the same number from the factor of 90, multiple of 6, and multiple of 9.
Then, check if it is higher than 10 but less than 20.
10<18<20
19. 36
FACTOR OF 72= 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
MULTIPLE OF 6= 6,12,18,24,30,36,42,48,54
Find the same number from the factor of 72 and multiple of 6. After that, check if that is an even number.
30<36<48, even number
20. 7
MULTIPLE OF 7= 7,14,21,28,35,42,49,56,63
FACTOR OF 7= 1,7
Find the same number and check the conditions.
7<28, odd number
