Answer & Explanation

ANS: 114
(1) equ =>10 + 10 + 10 = 30
(2) equ => X + 10 + 10 = 25 => X + 20 = 25=> X = 25 – 20 => X = 5
(3) equ => Y + 2X = 17 => Y + 2(5) = 17 => Y + 10 = 17 => Y = 17 – 10 => Y = 7
(4) equ => 2Y + X * 2(10 )=> 2(7) + 5 * 2(10) => 14 +( 5 * 20) => 14 + 100=114

Answer & Explanation

ANS: 114
(1) equ =>X + X + X = 30 => 3X = 30 => X = 10
(2) equ =>Y + 10 + 10 = 25 => 20 + Y = 25 => Y = 5
(3) equ =>Z + 5 + 5 = 17 => Z + 10 = 17 => Z = 7
(4) equ =>2Z + 5 × 2X = 14 +( 5 × 20) = 114 ( BODMAS METHOD)

Answer & Explanation

ANS: 199
(1) equ =>2X + 2X + 2X = 36 =>X = 6
(2) equ =>6 × 6 + Y = 44 =>36 + Y = 44 => Y = 8
(3) equ =>8 × Z + Z = 63 =>9Z = 63 => Z = 7
(4) equ =>7 + 2Y × 2X => 7 + (16 × 12) = 199 ( BODMAS METHOD)

Answer & Explanation

ANS: 9
(1) equ =>3 + 3 = 6
(2) equ =>3 + Y = 12 => Y = 9
(3) equ =>Z + 9 = 15 =>Z = 6
(4) equ =>3 + 6 = 9

Answer & Explanation

ANS: 44
(1) equ =>16 + 16 + 16 = 48
(2) equ =>6 + 6 + 6 = 18
(3) equ =>6 + Y + Y = 26 => 6 + 2Y = 26 => Y = 10
(4) equ =>2 +(6*8) – 6 =>2+48-6 => 50-6 =44
