Problem: The revenue of Pahang in 1899 amounted to only $62,077; in 1900 to $419,150.  In 1905 it was $528,368.  The expenditure in 1905 amounted to $1,208,176.  Of this sum $736,886 was expended on public works.  Pahang is still a source of expense to the federation, its progress having been retarded by the disturbances which lasted from December 1891 until 1895, with short intervals of peace, but the revenue was steadily increasing, and the ultimate financial success of the state is considered to be secure.  Pahang owed something over $3,966,500 to Selangor and $1,175,000 to Perak, which had financed it for some years out of surplus revenue.  The value of the imports in 1905 was $1,344,346, that of the exports was $3,838,928, thus making a total trade value of $5,183,274.  The most valuable export is tin, the value of which in 1905 amounted to $2,820,745. The value of the gutta exported exceeded $140,000, that of dried and salted fish amounted to nearly $70,000, and that of timber to $325,000.

Problem: The Senussi defeats in the Coastal Campaign forced the survivors over the border into Libya and to prevent a revival, the light Fords and armoured cars continued their patrols. The Aulad Ali surrendered to Peyton, having also gone hungry in the famine and public unrest in Alexandria diminished. The South African Brigade returned to Alexandria and two battalions of the Composite Brigade, a company of the Camel Corps, two guns of the Hong Kong Battery, the light armoured cars and the reconnaissance aircraft remained in Sollum, with an RFC half-flight. On 7 April, four light armoured cars and a machine-gun section of the 2/7th Middlesex left Sollum to raid an ammunition dump at Moraisa, 18 mi  to the north-west and destroyed artillery ammunition and about 120,000 rounds of small-arms ammunition; other patrols that month uncovered another 167,000 rounds. The Italian army posted two battalions at Bardia to co-operate and from 25-26 July, a raiding force from Sollum and Italian cars from Bardia, a party from the Camel Corps and an Italian yacht, Misurat attacked a party of about forty Muhafizia at Wadi Sanal in Libya, 40 mi  west of Ras el Mehl. The party was scattered and served as a warning that there was no sanctuary on either side of the border. Patrols continued for the year and a camel convoy was captured near Jaghbub, a Senussi stronghold 135 mi  from Sollum; more combined Italian-British raids were made during the winter.
Answer this question based on the article: How many is the difference between the amount in rounds of small arms ammunition found by the first patrol and the other patrols?
A:
147000
