Question
The average price of 10 stickers is Rs.12 while the
average price of 8 of these stickers is Rs.11.75. Of the remaining two stickers, if the price of one sticker is 60% more than the price of the other, then what is the price of each of these two stickers?Solution
Total cost of 10 stickers = 10*12 = Rs. 120 Total cost of 8 stickers = 8*11.75= Rs. 94 => The cost of remaining 2 stickers = 120- 94 = Rs. 26 Let the price of each sticker be x and y. => x + y = 26---------------- (1) And x = 160% of y = 1.6y => 2.6y = 26 y = 26/2.6= 10 and x = 26- 10= 16 So, the price of each of the two stickers is Rs. 10 and Rs. 16 respectively.
672 ÷ 28 × 24 + 363 – 309 =?
60 % of 640 - 57 × 2 - 1520 / 38 = ?
What will come in the place of question mark (?) in the given expression?
(√1089 + √484) X 5 + ? = 725
Simplify the following expressions and choose the correct option.
40% of 360 + 25% of 248 - 30
26% of 650 + 15% of 660 – 26% of 450 = ?
- What will come in the place of question mark (?) in the given expression?
2916 ÷ 54 = ? + 27
(392 + 427 + 226 – 325) ÷ (441 + 128 – 425) = ?Â
(8 x 9) ÷ 5 + ?2 = 23.4
