Question

Jax and Jane’s arrangement of magazines is given below.
Jax’s arrangement: 1 Hundred + 4 Tens + 5 Tens + 6 Ones
Jane’s arrangement: 2 Hundreds + 3 Tens + 4 Tens + 5 Ones.
How many magazines do they have in total?

• A. 461
• B. 481
• C. 467
• D. 471

Answer 1

The correct option is D 471

Jax’s arrangement: 1 Hundred + 4 Tens + 5 Tens + 6 Ones
$=100+40+50+6$
$=100+90+6=196$

Jane’s arrangement: 2 Hundreds + 3 Tens + 4 Tens + 5 Ones
$=200+30+40+5$
$=200+70+5=275$
$196+275=?$
Using the HTO table for decomposition:


$=300+160+11$
$=300+100+60+10+1$
$=400+70+1=471$

So, there are 471 magazines in total.
