|
Answer» Answer: I suppose that at 5 am the “crazy” CLOCK is synchronized with a “normal” one. From 5 am to 10 am the time elapsed in the “crazy” clock is 10 am - 5 am = 5 hours Then 5 X (60 + 5) = 300 + 25, which means the “crazy” clock is 25 MINUTES ahead of the “normal” one. Then in the “normal” clock the time elapsed from 5 am to 10 am is (5 x 60) - 25 = 275 minutes, or 275 / 60 = 4,58 hours = 4 hours + 0,58 of an hour 0,58 x 60 = 34,8 minutes Then the time in the “normal” clock is (5 am + 4h34,8min) = 9h34,8min rounded to 9h35min. |

A milkman purchases milk at the rate of ₹12 per litre and then mixes 25% of water to it.Find his profit %, if he sells the mixture at ₹15 per litre |
|
Answer» Let x LITRES of MILK be BOUGHT. Cost price of x litres of milk =Rs12x Quantity of milk after 25 % of water is added =x+ 100 25
x= 4 5x
litres Given, Selling price of 1 litre of milk =Rs15 => Selling price of 4 5x
litres =Rs 4 5x
×15=Rs 4 75x
Now, Profit % = C.P. S.P.−C.P.
×100= 12x 4 75x
−12x
×100= 48 75−48
×100=56.25 % |

Find the area of the quadrilateral AC=10cm BE=4cm DF=2cm |
|
Answer» Step-by-step explanation: ANSWER: We assume ABCD be the quadrilateral having SIDES AB, BC, CD, DA and ∠ACB = 90∘. We take a diagonal AC, where AC divides ABCD into TWO triangles ΔACB and ΔADC Since ∆ACB is right angled at C, we have AC = 15 cm; AB = 17 cm AB2 = AC2 + BC2
AREA of right angled triangle ABC, say A1 is given by , where, Base = BC = 8 cm; Height = AC = 15 cm Area of triangle ADC, say A2 having sides a, b, c and s as semi-perimeter is given by , where a = AD = 9 cm; b = DC = 12 cm; c = AC = 15 cm Area of quadrilateral ABCD, say A A = Area of ∆ACB + Area of ∆ADC Perimeter of quadrilateral ABCD, say P |
