The number of people who bought £4 tickets are 139.

<h3>How to illustrate the equation?</h3>

Let £4 tickets be x

Let £5 tickets be y.

Therefore based on the information given, this will be:

x + y = 223 ..... i

4x + 5y = 936 ..... ii

From equation i

x = 213 - y

Put this into equation ii

4x + 5y = 936

4(213 - y) + 5y = 936

852 - 4y + 5y = 936

Collect like terms

y = 84

This implies that the number of £5 tickets is 84.

Recall that x + y = 223

x + 84 = 223

x = 223 - 84

x = 139

The number of £4 tickets is 139

NOT is coded as LKF and FLY is coded as TNA, then which of the following word/s has/have correct coding? (1) TOP – FKJ (2) RUN –
AVprozaik [17]

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
