Help please needed 3 A Nepali student exchanged Rs 7,00,000
into
pound sterling of the rate of £1 = Rs 140
After hoo days,
Nepali currency is devaluated
by 5%. and he exchanged the pounds he
had into Nepali currency. again in that
day. What is his gain or loss? Find it.​

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

Y= -2x-1 the negative in front of the 2 is because the slope is negative and the -1 is because it’s down 1 on the y axis.
