Question

NTA14 +NTA15 =175229 FIND N+T+A

Answer 1

Answer:

21

Step-by-step explanation:

NTA14

=10000N+1000T+100A+10+4

NTA15

=10000N+1000T+100A+10+5

Adding these two we get

20000N+2000T+200A+20+9

=20000N+2000T+200A+29

But

20000N+2000T+200A+29=175229

20000N+2000T+200A+29=175200+29

20000N+2000T+200A=175200

200(100N+10T+A)=175200

100N+10T+A=175200/200

100N+10T+A=1752/2

100N+10T+A=876

100N+10T+A=100(8)+10(7)+6

this implies

N=8

T=7

A=6

Now

N+T+A=8+7+6=21
