Question
Marked price of an article is Rs.1400 more than the cost
price. When the same article is sold at a discount of Rs.300, the profit percent earned is 20%. To earn a profit of 30%, at what price the article should be sold?Solution
Let CP of an article be Rs.x And MP = Rs.(1400 + x) According to question, => (1400 + x) – 300 = [x × 120/100] => 1100 + x = 6x/5 => x = 5500 SP of an article = [(100 + 30)/100] × 5500 = Rs.7150
- Simplify:

1280 Γ· 8 + 490 Γ· β49 + ? = 150 * 2
1780 β 60 Γ· 4 x 80 = ?
- Find the simplified value of the given expression.

72% of 486 β 64% of 261 = ?
5760 ÷ 45 × 15 = ?
What will come in the place of question mark (?) in the given expression?
40% of 150 - ?% of 75 = 15 Γ 1.6
81% of 2300 – 34% of 550 = ?
The value of 97 Γ 103 is _________.
9/5 × 18/25 ÷ 42/21 = ? - 82/75
