Question
The selling price of a washing machine is Rs. 1680. If
the washing machine was sold at 40% profit, then find the discount offered given that the washing machine was marked Rs. 900 above its cost price.Solution
ATQ, Cost price of the washing machine = 1680 ÷ 1.40 = Rs. 1200 Marked price of the washing machine = 1200 + 900 = Rs. 2100 Required discount offered = 2100 - 1680 = Rs. 420
- (160 × 12 - 13 × 20)/(120 × 2 + 2 × 35 + 2 × 11) = ? 
- What will come in the place of question mark (?) in the given expression? - (308 – 154) ÷ 11 = ? ÷ 15 
- Simplify the expression:
 30% of [140% of (50 + 30) + 110] ÷ 70 × 100
- 4387897 – 3286871 – 51926 = ? 
- ? ÷ 8 = 2048 ÷ 64 
- 30% of 750 + ?% of 400 = 25% of 1016 + 3 
- What will come in place of (?) in the given expression. 
 
 
 (18.5 × 2) + (3.5 × 4) = ?
- 414 ÷ 23 × 38 – 154 + 264 = ? ...
- What will come in the place of question mark (?) in the given expression? - {180 + (2250/15)} ÷ 11 = ?2 + 14 
- The value of 15 × 14 – 30 + (32 + 17) is:
