Let the number be 3x and 4x respectively.

According to the question,

60% of 3x = 144

Or, 1.8x = 144

x = 144/1.8 = 80

Second number = 4x = 4 × 80 = 320

30% of second number = 30% of 320 = 0.3 × 320 = 96

456 – (76 + 15²) +  of

= 456 – (76 + 225) +

= 456 – 301 +

= 155 + 288

= 443

Hence, option A is the correct answer.

Hence, option D is the correct answer.

The set of letters “CRTP” is repeating thus the combination given in option (B) will complete the series as shown below:

CR T P/ C R T P/ C R TP

Hence, option B is the correct answer.
