काजूची किंमत प्रतिकिलो रु. 1,000 तर पिस्त्याची किंमत प्रतिकिलो रु. 1,200 आहे. जर काजू व पिस्त्याचे मिश्रण प्रतिकिलो रु. 1,050 विकले, तर त्या मिश्रणातपिस्त्याचे काजूशी असलेले प्रमाण किती?(गट क पूर्व-2018)

Answer»

Step-by-step EXPLANATION:

काजू:पिस्ता =1000:1200

total amount=1050

काजु=1050×1000/2200

=477₹

पिस्ता=1050×1200/2200

=573₹

काजुचे प्रमाण= 477/1000

=0.477 किलो

पिस्ता प्रमाण=573/1200

=0.4775 किलो

explaination: 2200=1000+1200

Find a scale with a unit of 1 and choose the correct answer (for example, 1 cm=7 yards).Car and model carScale: _____1 in = 10 ft1 ft=18 in1 in = 3.6 ft1 ft=11 in

Answer»

Answer:

Length :

10 millimeters (MM) = 1 centimeter (cm)
10 millimeters (mm) = 1 centimeter (cm) 10 centimeters = 1 decimeter (dm) = 100 millimeters
10 millimeters (mm) = 1 centimeter (cm) 10 centimeters = 1 decimeter (dm) = 100 millimeters10 decimeters = 1 meter (m) = 1,000 millimeters
10 millimeters (mm) = 1 centimeter (cm) 10 centimeters = 1 decimeter (dm) = 100 millimeters10 decimeters = 1 meter (m) = 1,000 millimeters10 meters = 1 dekameter (DAM)
10 millimeters (mm) = 1 centimeter (cm) 10 centimeters = 1 decimeter (dm) = 100 millimeters10 decimeters = 1 meter (m) = 1,000 millimeters10 meters = 1 dekameter (dam) 10 dekameters = 1 hectometer (hm) = 100 meters
10 millimeters (mm) = 1 centimeter (cm) 10 centimeters = 1 decimeter (dm) = 100 millimeters10 decimeters = 1 meter (m) = 1,000 millimeters10 meters = 1 dekameter (dam) 10 dekameters = 1 hectometer (hm) = 100 meters10 hectometers = 1 kilometer (km) = 1,000 meters

Volume

10 milliliters (ml) = 1 centiliter (cl)
10 milliliters (ml) = 1 centiliter (cl) 10 centiliters = 1 DECILITER (dl) = 100 milliliters
10 milliliters (ml) = 1 centiliter (cl) 10 centiliters = 1 deciliter (dl) = 100 milliliters10 deciliters = 1 liter (l) = 1,000 milliliters
10 milliliters (ml) = 1 centiliter (cl) 10 centiliters = 1 deciliter (dl) = 100 milliliters10 deciliters = 1 liter (l) = 1,000 milliliters10 liters = 1 dekaliter (DAL)

337.	The speed of a boat in a still river is 10km/h. It is not influenced by the river.The speed of the river is 3km/h. It is not influenced by the speed of the boat.The boat's speed moving along the river is 10 + 3 = 13 (km/h)The boat's speed moving against the speed of the river is 10 - 3 = 7 (km/h)Let's say out of curiousity we substract the boat's speed along the river (13km/h) by the speed of the boat against the river (7km/h) and we get 13 - 7 = 6 (km/h)We see that the substraction equates to twice the speed of the river (6km/h / 2km/h = 3km/h).

Answer» Answer: 15 km/h north Step-by-step EXPLANATION:

337.

The speed of a boat in a still river is 10km/h. It is not influenced by the river.The speed of the river is 3km/h. It is not influenced by the speed of the boat.The boat's speed moving along the river is 10 + 3 = 13 (km/h)The boat's speed moving against the speed of the river is 10 - 3 = 7 (km/h)Let's say out of curiousity we substract the boat's speed along the river (13km/h) by the speed of the boat against the river (7km/h) and we get 13 - 7 = 6 (km/h)We see that the substraction equates to twice the speed of the river (6km/h / 2km/h = 3km/h). Why is that? is there a mathematical principal/law that can explain this phenomenon?

Answer» Answer: Step-by-step EXPLANATION: X+y=85 x-5=4(y-5) x-5=4y-20 therefore x=4y-15 substituting in 1 we get 5y-15=85 5y=100 therefore y=20 x=85-y 65 thus VALUES of x and y are 65 and 20 respectively x=69

342.

the sum of the ages of a father and his daughter is 85yrs. five years ago, the father was exactly four times as old as his daughter. the present age of the father is?

Answer»

Answer:

Step-by-step EXPLANATION:

X+y=85

x-5=4(y-5)

x-5=4y-20

therefore x=4y-15

substituting in 1 we get

5y-15=85

5y=100

therefore y=20

x=85-y

65

thus VALUES of x and y are 65 and 20 respectively

x=69
