Prove thatI 2473.2 sin-1-tan-Äą |
|
Answer» Let y= arcsin(3/5), then what this means is sin(y)= 3/5, using the fact that (sin(y))^2 + (cos(y))^2=1 we can obtain that cos(y) = 4/5 therefore tan(y) = 3/4 now we use that tan(x+w) =[tan(x) + tan(w)] / [ 1 - tan(x) tan(w)] by taking x=w we see that tan(2x) = 2tan(x) / [ 1 - tan(x)^2] then tan(2y)= 2(3/4) / [1 - (3/4)^2] = 24/7 then arctan (24/7) = 2y = 2 arcsin(3/5) |

An article was purchased for? 1 239 including GST of 1 8%. Find the price of thearticle before GST was added? |
|
Answer» Cost with gst included = rupees 1239 Cost with out gst = x rupees gst = 18% If we take this into equation - x + ( ( 18 ÷ 100 ) × x ) = 1239 cost before gst + gst = cost with gst x + ( 9x ÷ 50 ) = 1239 ( 50x + 9x ) ÷ 50 = 1239 59x ÷ 50 = 1239 59x = 1239 × 50 59x = 61950 x = 61950 ÷ 59 x = 1050 Price before GST = 1050 rupees Like my answer if you find it useful! |

On selling a TV at 5% gain and a fridge at 10% gain, a shopkeeper gains? 2000, Butif he sells the TV, at 10% gain and the fridge at 5% loss, he gains Rs.1500 on thetransaction. Find the actual price of the T.V. and the fridge.6.7. Two numhers are in the ratiA |
|
Answer» Solution :- Let the actual price of the TV be Rs. 'x' and of the fridge be Rs. 'y'. Situation -1 By selling the TV at 5 % gain and fridge at 10 % gain, the shopkeeper gains Rs. 2000. ⇒ 5x/100 +10y/100 = 2000 ⇒ x/20 + y/10 = 2000/1 Taking the L.C.M. of the denominator and then solving it, we get. ⇒ (x + 2y)/20 = 2000 ⇒ x + 2y = 40000 ...........................(1) Situation - 2 By selling the TV at 10 % gain and fridge at 5 % loss, the shopkeeper gains Rs. 1500. The loss is indicated with the negative sign. ⇒ 10x/100 - 5y/100 = 1500 ⇒ x/10 - y/20 = 1500/1 Taking the L.C.M. of the denominator and then solving it, we get. ⇒ (2x - y)/20 = 1500 ⇒ 2x - y = 30000 ........................(2) Now, multiplying the (1) by 2, and then subtracting 2 from it, we get. First Multiplying (1) by 2 = 2*[(x + 2y) = 40000] ⇒ 2x + 4y = 80000 Now, subtracting (2) from the above. 2x + 4y = 80000 2x - y = 30000 - + - ________________ 5y = 50000__________________ ⇒ 5y = 50000 ⇒ y = 50000/5 ⇒ y = 10000 The actual price of fridge is Rs. 10000. Now putting the value of y = 10000 in (1), we get. ⇒ x + 2y = 40000 ⇒ x + (2*10000) = 40000 ⇒ x = 40000 - 20000⇒ x = 20000 Hence, the actual price of TV is Rs. 20000 and actual price of fridge is Rs. 10000.

The marked price of an article is? 3,500 and rate of GST is 12%. A shopkeepallows a discount of 20% and still makes a profit of 10%. Find the original coprice of the article and the selling price including GST |
|
Answer» The market price is 3,500 . So GST(12%) value will be 0.12*(3500) = 420 Now total market price is 3500+420 = 3920 Now suppose the selling price is X. so, on giving discount of 20% the selling price would be (100-20)%*(x) = 0.8x Now profit % = sp-cp/cp => 0.1 =( 0.8x-3920)/3920 => 392 = 0.8x -3920 so, 0.8x = 3920+392 = 4312. so x = 4312/0.8 = 5390 the selling price is 5390. no answer is Rs 2850.90;Rs 3136 |
