Question
In 2019 when his income was Rs. 40,000, Ramesh spent 50% of
his income and saved the rest. In 2020, if his income increased by 10% and his expenditure increased by Rs. 1,000, then by how much did his savings increase as compared to that in 2019?Solution
ATQ,
Amount spent by Ramesh in 2019 = 40000 × 0.5 = Rs. 20,000
Amount saved by Ramesh in 2019 = 40000 - 20000 = Rs. 20,000
Income of Ramesh in 2020 = 40000 × 1.1 = Rs. 44,000
Amount spent by Ramesh in 2020 = 20000 + 1000 = Rs. 21,000
So, amount saved by Ramesh in 2020 = 44000 - 21000 = Rs. 23,000
Increase in savings as compared to 2019 = 23000 - 20000 = Rs. 3,000
- What will come in the place of question mark (?) in the given expression?
(198/13) X (52/11) - ? ÷ 5 = 13 + 68 ÷ 4 1780 – 60 ÷ 4 x 80 = ?
(1/8) × (256 × 2)/(8 × 4) + ?3 = 1730
What will come in the place of question mark (?) in the given expression?
1*1/2 + 11*1/3 + 111*1/2 + 1111*1/3 + 11111*1/3 =?
What will come in the place of question mark (?) in the given expression?
40% of 150 - ?% of 75 = 15 × 1.6
9999² + 1111² =?
What will come in the place of question mark (?) in the given expression?
? = {1026 ÷ 54 + 17 × 13 – (384 ÷ 24)}Â
- What will come in place of (?), in the given expression.
144 ÷ √36 + 13² – 100 = ? 8 × 9 + ? – 6 × 11 = 12 × 8
