Answer:
3 and 12
Step-by-step explanation:
3*5=15 and 15-3=12. The product of 3 and 12 is 36.
Answer: <u><em>The first number is 8</em></u>
Step-by-step explanation: Let the three No. s be x, y and z respectively
given = x+ y+ z= 72
y=7x
z=7x-18
∴As we know x+ y+ z=72
i.e. x+7x+7x-18=72
15x=72+18=90
15x=90
x=90/15
∴x=8
∴y=7x
7×8=56
∴z=7x-18
56-18=38
∴<u><em>The first no. is x=8</em></u>
<u><em>The second no. is y=7x = 56</em></u>
<u><em>The third no. is z=7x-18 = 38</em></u>
Greater than 20 because 5×6=30 so it passed
