Pls tell urgent A lady went to a bank with Rs. 1,00,000. She asked the cashier to give her Rs. 500 and Rs. 1,000 currency notes in return. She got 175 currency notes in all. Find the number of each kind of currency notes.

Let the number of Rs 500 be x

and no. of Rs 1000 be 175-x

ATQ, 500x + 1000 (175-x) = 100000

500x = 75000

x = 75000/500 - 150

Therefore, no. of Rs.500 notes = x = Rs.150

and no. of Rs.1000 notes - 175 - x - 175 - 150 = 25

Hope that this was helpful :)

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
