You can do this by cross multiplying
Answer:
- (1) and (3) are correct options
Step-by-step explanation:
- NOT is coded as LKF
- FLY is coded as TNA
<u>Using alphabet, we can see that:</u>
NOT = 14, 15, 20 ⇔ 13+1, 13+2, 13+7 ⇒ LKF = 12,11,6 = 13-1, 13-2, 13-7
Coding for each letter is 13 + x ⇒ 13 - x
(1) TOP ⇒ FKJ
- TOP = 20,15,16 ⇒ 13-7, 13-2, 13-3 = 6,11,10 = FKJ
- Correct
(2) RUN ⇒ IFM
- RUN = 18,21,14 ⇒ 13-5,13-8,13-1 = 8,5,12 = HEL ≠ IFM
- Incorrect
(3) MUG ⇒ MES
- MUG = 13,21,7 ⇒ 13+0, 13-8, 13+6 = 13,5,19 = MES
- Correct
(4) HOT ⇒ RKG
- HOT = 8,15,20 ⇒ 13+5,13-2, 13-7 = 18,11,6 = RKF ≠ RKG
- Incorrect
(7-2)2=5*2=10
or
(7-2)2=7*2-2*2=14-4=10
X1+X2 Y1+Y2
--------- , ---------
2 2
Thats the equation. You write that (the equation above) in parentheses.
