Let income of Rishu be 100 Saving of Rishu = 100 × (x/100) = x Expenditure of Rishu = 100 – x Rishu's salary after increment = 100 × (126/100) = 126 Rishu's expenditure after increment = (100 – x) × 120/100 = (100 – x) × 6/5 New Saving = 126 – (100 – x) × 6/5 ----(1) New saving after increment = x × 150/100 New saving after increment = 3x/2 ----(2) From eq. (1) and eq. (2) ⇒ 126 – (100 – x) × 6/5 = 3x/2 ⇒ 126 – 120 + 6x/5 = 3x/2 ⇒ 6 = (3x/2) – (6x/5) ⇒ 6 = (15x – 12x)/10 ⇒ x = 20 ∴ The value of x is 20
360 × 9 ÷ 3 + 120 + 900 ÷ 5 = ?
72 x 60 x 22 x 32 =?
(13)2 + 6 × (19)2 – 312 × 4 = ?
(65% of 120) = 25% of ? - 22
25% of 1000 + 10% of 150 – 22 × ? = 45
464 + 181 +? = (154 × 25) - (15) 2
(13)2 - 3127 ÷ 59 = ? x 4
The value of 97 × 103 is _________.
400 % of 20 + 65 % of 620 - 92 × 5 = ?
