Let the number of toffees bought at the rate of Rs 20 for 50 be "a"
Then total money invested in these toffees = 20/50 x a = 2a/5
Number of toffees brought at the rate of Rs1.50 each = 2a
Total money invested in these toffees = 1.50 x 2a = 3a
Total cost of toffees to Mohan = 2a/5 + 3a = 17a/5
Total revenue realized by selling them at 20 for Rs 12 = 12/20 x (a + 2a) = 9a/5
Overall loss is 200
So,
17a/5 - 9a/5 = 200
8a/5 = 200
a = 125
total number of toffees purchased = 3a = 375
150% of 850 ÷ 25 – 25 = ?% of (39312 ÷ 1512)
[4(1/2) + 4(1/3)] × 12 – 42 = ?2
`(450 -: ?)/(2.5 xx 1.2)` = 250
520% of 360 – 12% of 400 = ? x 4
(18 × 9 ÷ 6) × 3 = ?
The speed of the stream is 10 km/h. Boat ‘A’ covers 110 km distance against the stream in 11 hours and boat ‘B’ covers 65 km distance against th...
18(1/3) + 9(2/3) – 10(1/3) = 1(2/3) + ?
1280 ÷ 8 + 490 ÷ √49 + ? = 150 * 2
1550 ÷ 62 + 54.6 x 36 = (? x 10) + (28.5 x 40)
