Question

Find : (60 x 1) + (400 ? 10) ? 60 = ________ x 2 (a)45 (b)20 (c)30 (d)55

Answer 1

Answer:

(60×1) + (400/10)-60=20×2

Answer 2

Find :

(60 x 1) + (400 ? 10) ? 60 = ________ x 2

(a)45 (b)20 (c)30 (d)55

$LHS = ( 60 \times 1 ) + ( 400\red{ \div }10) \red{- }60$

$= 60 + \frac{400}{10} - 60$

$= 60 + 40 - 60$

$\green {= 40 }$

$RHS = \pink {20} \times 2$

$\green {= 40}$

Therefore.,

$( 60 \times 1 ) + ( 400\red{ \div }10) \red{- }60$

$\green { = 20 } \times 2$

$Option \: \pink { ( b ) } \: is \: correct.$
